AUG 2, 2018

TN

tennessee

Races to Watch: TN Sen

Tennessee's nine districts are not ranked as competitive, though the Senate seat left open by Republican Bob Corker's retirement, reconsideration and final decision to retire has sparked an interest on both sides of the aisle. It will be a tough race for Democrats, though popular former Gov. Phil Bredesen could give the GOP a run for its money, even though Trump won the state by 26 points. CNN ranks this race as lean Republican.

AUG 7, 2018

OH

Ohio (Special Election)

Races to watch: OH-12 special election

Special election for former GOP Rep. Pat Tiberi's seat. Tiberi resigned to join the Ohio Business Roundtable. CNN rates this Columbus-suburb district as lean Republican.

KS

kansas

Races to watch: KS-02 (open, Jenkins), KS-03 (Yoder)

The Kansas side of Kansas City is a potential risk for Republicans. As GOP Rep. Kevin Yoder seeks a fifth term, he's weighed down by a district that narrowly voted for Clinton in 2016. Yoder's cash advantage gives him a good start, as CNN rates this race as lean Republican. Retiring GOP Rep. Lynn Jenkins' seat is also rated as lean Republican.

MI

michigan

Races to watch: MI-06 (Upton), MI-07 (Walberg), MI-08 (Bishop), MI-11 (open, Trott)

Four Michigan Republican-held seats are viewed as competitive by CNN, leading with retiring Rep. David Trott's Detroit-suburb district ranked as toss-up. Rep. Michael Bishop will seek a third term in his Lansing-based district, where Trump expanded the margin of the two past presidential winners, though he's been outraised by his Democratic opponent. CNN rates this race as lean Republican. A good night for Democrats in November could put GOP Reps. Fred Upton and Tim Walberg at risk, but for now, their races are ranked as likely Republican.

MO

missouri

Races to watch: MO Sen

Democratic Sen. Claire McCaskill will most likely face the toughest race she's experienced as she seeks a third term. Coming off the heels of Trump's 19-point win, Republicans are intent on flipping this seat in the Show Me state to their side. Josh Hawley – Missouri's Republican Attorney General – is McCaskill's likely GOP opponent. Democratic strength nationwide helped McCaskill in 2006 and 2012, which makes her party's momentum heading into November a critical factor in this race.

WA

washington

Races to watch: WA-05 (McMorris Rodgers), WA-08 (open, Reichert)

GOP Rep. Dave Reichert's retirement gives Democrats a big opening in this district of Seattle suburbs where Clinton won in 2016. CNN rates this race as a toss-up. House Republican Caucus leader Cathy McMorris Rodgers has a significant money lead and history in the district, giving her a significant advantage over her Democratic rivals, but momentum on the left cannot be ignored in this east Washington district. CNN ranks this race as likely Republican. Democratic Sen. Maria Cantwell is up for re-election.

AUG 11, 2018

HI

hawaii

Races to watch: HI-01 (Hanabusa); Governor

Democratic Sen. Mazie Hirono is running unopposed in her primary on August 11, as is GOP challenger Michael Hodgkiss, in a race that CNN has rated solid Democratic. Hawaii’s two U.S. House races feature only slightly more competitive contests, with contested primaries for seats likely to stay in Democratic hands. In the 2nd district, Rep. Tulsi Gabbard is a popular incumbent, although the Hawaii Teachers Association switched their endorsement to Democratic challenger Sherry Alu Campagna last month, citing Gabbard’s failure to adequately condemn chemical weapons attacks by Syrian Dictator Bashar al-Assad amid his country’s civil war. The 1st district features a competitive open seat Democratic primary, though no Republicans have entered the race, after Democratic Rep. Colleen Hanabusa launched a bid for governor against incumbent Democrat Gov. David Ige. Running in the 1st district primary are Lt. Gov. Doug Chin, former U.S. Rep. Ed Case, three state lawmakers – Rep. Beth Fukumoto, Rep. Kaniela Ing, and Sen. Donna Kim – and Ernie Martin, a Honolulu city councilman.

In the governor’s race, Hanabusa has made a spirited primary bid against Ige, even earning the endorsement of former Lt. Gov. Shan Tsutsui who served alongside Ige for two years. The winner of the Democratic primary is likely to win the general election in the deep blue state.

AUG 14, 2018

CT

connecticut

Races to watch: Governor

Gov. Dannel Malloy announced he would not seek re-election to a third term last year, setting off a competitive gubernatorial race in 2018. Democratic businessman Ned Lamont and GOP New Britain Mayor Erin Stewart are the favorites to emerge from crowded primary fields.

Democratic Sen. Chris Murpy is up for re-election this year in a race CNN rates solid Democratic – Murphy is unopposed in his primary, and likely to face Republican Dominic Rapini in the general election. There are no Connecticut contests on CNN’s list of Key House races in 2018, though the 6th district features an open seat race after Rep. Elizabeth Etsy announced she would not seek re-election in the wake of reports that she had protected a staffer accused of sexual harassment. Democrat Mary Glassman leads a muddled primary race for that seat.

MN

minnesota

Races to watch: MN-01 (open, Walz), MN-02 (Lewis), MN-03 (Paulsen), MN-07 (Peterson), MN-08 (open, Nolan)

Four congressional districts in Minnesota are ranked as toss-ups by CNN. Two Democratic-held seats by retiring Reps. Tim Walz and Rick Nolan are targets for Republicans, hoping to use Trump's wins as a springboard to victory. Democrats are heavily targeting two suburban Minneapolis Republicans – freshman Rep. Jason Lewis, and five-term Rep. Erik Paulsen. Democratic Sen. Tina Smith is running to serve the rest of former Sen. Al Franken's term. Democratic Sen. Amy Klobuchar is up for re-election. Both are heavy favorites to win.

VT

vermont

Races to watch: Governor

Vermont features a competitive and quirky gubernatorial race, as incumbent Republican Phil Scott is seeking re-election in a typically blue state against a curious group of challengers. Scott looked to face a primary challenge from Keith Hern before Hern decided to run as a Democrat in a crowded field featuring Christine Halliquist, James Ehlers, Brenda Siegel, and 14-year old Ethan Stoneborn (Vermont and Kansas are two states that have no age requirement on running for governor).

Bernie Sanders – who nearly captured the Democratic nomination for president in 2016 – is running for re-election to the U.S. Senate, in a race likely to be far less competitive than two years ago. Sanders won by 46 points in 2012, and doesn’t look to face much stiffer competition this time around. In the state’s lone congressional district, incumbent Democratic Rep. Peter Welch is also likely to face minimal opposition on his way to re-election, with two fringe challengers in his primary contest.

WI

wisconsin

Races to watch: WI Sen; WI-01 (open, Ryan), WI-03 (Kind), WI-06 (Grothman), WI-07 (Duffy)

Paul Ryan's retirement has put his Janesville-based seat in play, where Democratic challenger Randy Bryce had already raised millions. CNN rates it as lean Republican. Democratic Sen. Tammy Baldwin will face a tough re-election in the Badger State, coming off Trump's historic 2016 win there. A Republican presidential candidate hadn't won the state in the 28 years prior. CNN currently rates this race as lean Democrat.

AUG 21, 2018

AK

alaska

Races to watch: Governor

In Alaska, the premier contest is the governor’s race, where independent incumbent Gov. Bill Walker is seeking re-election. Former U.S. Sen. Mark Begich is running unopposed in the Democratic gubernatorial primary – Walker had considered running for re-election as a Democrat, but chose to avoid facing off with Begich in the Dem primary. On the Republican side, former Lt. Gov. Mead Treadwell headlines a competitive GOP field featuring former state Rep. Scott Hawkins, former state Sen. Mike Dunleavy, and businessman Scott Hawkins.

U.S. Rep. Don Young is up for re-election. He faces little in the way of a primary challenge, and will likely see Democrat Dimitri Shein and strong independent candidate Alysa Galvin in the general election, though Young’s seat is not on CNN’s of Key House races and likely safe.

AUG 28, 2018

AZ

arizona

Races to watch: AZ Sen; AZ-01 (O'Halleran), AZ-02 (open, McSally), AZ-09 (open, Sinema)

If Democrats have any chance of taking back the Senate, they will have to win in Arizona. Republican Jeff Flake's retirement opened the seat up, and both sides are already campaigning hard for it. Trump's immigration policies and positions will most likely embolden supporters and detractors to come to the polls in the Grand Canyon State, which he won by only 4 points in 2016. The race is ranked as a toss-up by CNN. Rep. Kyrsten Sinema is the likely Democratic nominee. Republicans will choose between Rep. Martha McSally - whose district is now lean Democrat - former Sheriff Joe Arpaio and former state Sen. Kelli Ward.

FL

florida

Races to watch: FL Sen; FL-06 (open, DeSantis), FL-07 (Murphy), FL-13 (Crist), FL-15 (open, Ross), FL-18 (Mast), FL-26 (Curbelo), FL-27 (open, Ros-Lehtinen)

Democrats could show some strength in Florida, where one Republican-held seat is already ranked as a toss-up by CNN. GOP Rep. Carlos Curbelo is in danger of losing his seat composing the southern tip of the state. GOP Rep. Ron DeSantis is running for governor, and fellow GOP Rep. Dennis Ross is retiring. CNN ranks these seats -- as well as that of Republican Brian Mast -- as likely Republican. Democrat Bill Nelson faces a tough re-election to the Senate against Republican Gov. Rick Scott, who announced his run in April and has deep pockets. CNN rates this as a toss-up, and it will likely be one of the most expensive Senate races of the cycle.

NH

new hampshire

Races to watch: NH-01 (open, Shea-Porter), NH-02 (Kuster)

Both of New Hampshire's congressional seats are viewed as competitive this year. Democratic Rep. Carol Shea-Porter's district has flipped between both parties multiple times over the past decade. This seat is currently ranked as a lean Democrat by CNN. Democrat Ann Kuster's race will most likely not be as as competitive, but both parties have the history and know-how to win in the Granite State. CNN currently ranks this race as likely Democrat.

ME

maine

Races to watch: ME-02 (Poliquin)

Democrats would like to take back the last Republican-held seat in Maine's 2nd District, but that could prove tougher than expected. The district's support of Trump (giving him an electoral vote in 2016) and Rep. Bruce Poliquin's strong cash advantage will be tough to beat in this northern Maine seat. CNN currently rates the race as lean Republican, though the governor's race could provide Democrats a place to flip a state executive seat from red to blue. Independent Sen. Angus King is up for re-election.

JUNE 5, 2018

MS

mississippi

Incumbent Sen. Roger Wicker cruised to re-nomination in the Mississippi;’s GOP Senate primary, after avoiding a primary challenge from conservative firebrand State Sen. Chris McDaniel. McDaniel will instead be running in an open-party special election for Mississippi’s other U.S. Senate seat on Election Day, the result of GOP Sen. Thad Cochran’s resignation from his seat amid health issues in April. Democrats Howard Sherman and David Baria advanced to a run-off for the Democratic nomination in the race against Wicker. Meanwhile, in the 3rd district Republican primary, Michael Guest and Whit Hughes advanced to a run-off after neither candidate received 50% of the vote.

OR

oregon

In Oregon, incumbent Democratic Gov. Kate Brown easily won re-nomination. She heads to a general election contest against Republican primary winner Knute Buehler, who defeated second-place finisher Sam Carpenter by over 15 points. Brown is favored to win re-election in the reliably blue state. Oregon’s lone Republican U.S. House incumbent, Rep. Greg Walden, also breezed through his primary, and he will face Jamie McLeod-Skinner, the winner of the 2nd district Democratic primary, in the general election.
