Unironically, I think that was the thought process.
Hard to vote for someone who is telling you all is well and the people that got the country here are competent and mean well, when the country is going through 5 different crises, all preventing you from living a decent life.
Nobody ever accused voters of being smart. That said, Harris lost a lot of Biden's 2020 voters, so this is the exact good time to go super critical on her campaign.
