Governor Tim Walz grilled on 'major mistake' of Biden seeking re-election

"History will tell us to go back on that. That very well could be the case, Jake. What I'm concerned about is learning from those lessons. I would hope we would never do it again, make a mistake, make sure we go through and get someone. But I don't know where it helps us going forward," Walz said, before pivoting to Trump. 

"What does 'I told you so' really mean here? I mean, people heard her message. They did not vote for her. She lost every battleground state. You yourself have criticized the Harris-Walz campaign for being too cautious. She may have told the American people, you know, she may have warned the American people, but she didn't do it compellingly enough to win," the CNN host said. 

Walz said he owned the loss and criticized himself for it. However, he said Harris tried to warn people of what Trump was planning to do.  

The CNN host also asked about criticisms that the Democratic Party was gaslighting Americans about inflation, the border and Biden's fitness. 

"And then, fundamentally, this idea that President Biden was up for another four years of the job while Americans in poll after poll, for year after year, were saying, 'He's too old to do the job,' your party stood against all of those things," Tapper said.
