Sanders says he's looking forward to Sunday's debate with Biden
Bernie Sanders, speaking in Vermont a day after losing several Democratic contests, vowed to ask Joe Biden tough questions at Sunday's debate.
"On Sunday, I very much look forward to the debate in Arizona with my friend, Joe Biden. And let me be very frank as to the questions that I will be asking Joe," said Sanders who went on to list a series of questions he planned to ask the former vice president.
The Vermont senator wrapped up his speech with a promise to "do everything in my power" to defeat President Trump.
"Donald Trump must be defeated, and I will do everything in my power to make that happen," he said.
Sanders continued: "On Sunday night, in the first one-on-one debate of this campaign, the American people will have the opportunity to see which candidate is best positioned to accomplish that goal."

Sanders says last night "was not a good night" for the campaign
Speaking after big Super Tuesday losses to Joe Biden, Sen. Bernie Sanders said last night "was not a good night for our campaign from a delegate point of view."
"We lost in the largest state up for grabs yesterday, the state of Michigan. We lost in Mississippi, Missouri, and Idaho," he added.
Sanders noted that he won North Dakota and is currently leading in Washington state.
"Poll after poll, including exit polls, show that a strong majority of the American people support our Progressive agenda," said Sanders, who spoke from Burlington, Vermont.

Sanders will deliver remarks in Burlington today
From CNN's Ryan Nobles
Sen. Bernie Sanders will deliver remarks at 1 p.m. ET in Burlington, Vermont.
A source with knowledge of his plans says Sanders is expected to announce he is staying in the race and looks forward to a debate with Joe Biden.
The speech comes one day after Super Tuesday II. CNN has projected he will win just one state — North Dakota.

Voter turnout increased in Michigan, Mississippi and Missouri yesterday
The largest bump was in Michigan, where turnout was up by 30.5%, and they are still counting the votes. CNN has projected former Vice President Joe Biden will win in Michigan, which will be a pivotal state in the general election this fall.
Turnout was up more than 17% in Mississippi and more than 5% in Missouri.
It’s not easy to draw comparisons in the other states that held contests on Super Tuesday II: Washington state, Idaho and North Dakota. That's because they held caucuses in 2016 but changed their formats for 2020, holding primaries or party-run caucuses that closely resemble traditional primaries.
It’s clear from the numbers that primaries lead to higher turnout than caucuses.
