People voted against however things were because of the pandemic. Trump was in charge, so he caught the general dissatfication with everything.

Now the sting of inflation last year likely has a lot of those same people again upset at how things are and vote for change again, whoever it will be.

Also, 2020 was the most accessible election in history, with so much flexibility for remote voting and so many people not stuck at work unable to find time to vote. The gop has been changing that, locking down absentee voting more, successfully getting voting id laws passed, and reducing early voting sites and hours. People are too busy working at their workplace again, and access to voting is reduced.
