 For NPR News in the Twin Cities, I'm Kelly Blyer. Minnesota Governor Tim Walz still expects President Joe Biden to be the Democratic nominee after his performance heightened anxiety within the party. Walz went on Fox News this morning to defend Biden's ability to do the job for another term. Biden had many unsteady moments in last night's CNN debate with former Republican President Donald Trump. Walz says voters should evaluate the candidates' records, not how they come off in a debate.
