Trump recieved more votes in 2020 than 2016. So that theory is out. And when in the end it came down to 10,000's votes among swing states those votes mattered in 2016, and 2024.
Well at least you blame Biden. Now when you can blame Harris, who failed to do her job and remove him as VP, and the Dem leadership who covered up his cognitive decline, then maybe you can come around to the rot in the party. The bad policy they have, the abandoned middle class and working class they left behind, and realize they are not the party of the people.
Then they can start to win. And not just expect to.
