Sen. Joe Donnelly is one of five Democratic senators up for re-election in states that President Trump won by double digits. Donnelly will face businessman Mike Braun, who defeated two members of Congress in the Republican primary. Recognizing he represents a conservative state, Donnelly has worked to align himself with Trump at times. Like many Democrats, though, he's focusing his campaign on health care. Winning re-election as a Democrat in a state that voted for Trump by 19 points won't be easy, but Donnelly won his first term in 2012 despite President Obama losing Indiana (one of the two states that voted for Obama in 2008 but not 2012). Republican Reps. Jackie Walorski, who represents the 2nd District, in the South Bend area, and Trey Hollingsworth, from the 9th District, around Bloomington, both could be vulnerable to Democratic challengers. Republican Greg Pence, the older brother of Vice President Mike Pence, is heavily favored to win in the 6th District.
