A month ago, the third night of the Democratic National Convention was supposed to be Vice President Kamala Harris' night. But after President Joe Biden surprised Democrats by dropping out of the 2024 race, Wednesday's event in Chicago will be the moment voters are introduced to Minnesota Gov. Tim Walz instead.

Lauded by the left for his policies on free school lunches, abortion and the state's "trans refuge" law, Walz has been chastised by conservatives for raising taxes to pay for it all and credit him for the state's lagging economy. Walz's record – military or otherwise – has been a popular talking point since Harris announced her vice presidential pick earlier this month. Will he come out swinging and defend it onstage? Or tone down his "Midwest Nice" "weird" jabs in an appeal to moderate voters?
