Well one good example is border encounters and illegal migration. It was an important issue and what was the Harris/Democrat solution to the below graph? If I thought illegal migration was a problem and I had to go on perceptions alone then I'd say Trump was stronger so surely therefore I'd vote for Trump?
It isn't good enough or powerful enough to say that nobody should vote for Trump and so therefore you have to vote Democrat. If I fundamentally dislike gender politics for example then why would I vote for somebody on the polar opposite end of it? To some people on many issues Trump was actually the lesser evil. If it was more about these fundamental policy issues then the Democrats lost because they provided the wrong answers and thought pulling out Beyonce would make the difference.
We're having the same problem on immigration in the UK. The last government had no idea and the current one doesn't either so they just ignore it. The only party offering some sort of solution is Reform and that's why they're leading the polls. If the status quo remains until the next election (which it probably will) then there is a real possibility that Reform could win power. The same is happening across Europe with the far-right rise and populism.
