Look, if no one here wants to even look into how the other side thinks, then you are doing yourselves a huge disservice.
TLDR:
Trump. Is. The. Problem. With everything. You want to have a discussion, you need to stop the guy with the bullhorn from drowning out the discussion.
You want to have a serious discussion about what republicans think - which I respect - but you will never get to that point with Trump. Its just not going to happen. There is a cognitive dissonance at play here - You take Trump seriously, even if you don't like him and never will. I do not, and can not. Not because I'm a lib, or biased... but because I can't take someone with the IQ of a gnat and the empathy of a komodo dragon seriously.
Do a balance sheet. Mark down all of Trump's accomplishments, and I'll give them all to you without debate. January 6 renders every one of them moot.
You think there's a problem with vaccines? Fine. Pick a different leader who can explain it better. Watching a guy who's selling goofy shoes try to outshine career public servants, scientists and doctors by suggesting shining a light up your ass or injecting disinfectant - on a national stage - is not going to help move that discussion along. Issues with the border? A wall is a simpletons solution to a complex issue. Pick someone who can better explain his policy position. Abortion? Punish the woman - coming from a rapist and a guy who I'd bet the house on having paid for at least a few, and even if he didn't, he's a sleaze. Pick someone else.
Would you want to sit down with me and come to some sort of consensus if I was legit arguing for Kanye West to be president? He and Trump are not that unlike. Would you respect that decision? Kanye at least isn't the reason for hundreds of incarcerations and an insurrection on the Capitol. Or even an unruly visit, if you disagree with the characterization. Trying to convince me on the merits of Trump, or even why anyone would support him, is something that is still a mystery, because none of the answers make any sense. Your reasons for wanting a conservative president or not supporting democrat policies may make PERFECT sense, but it all falls apart when you interject that dimwit into the convo.
Also, what does it say that Americans were presumably happier under Trump and still got rid of him? That's a valid question, right? What do you think the answer would be from the typical Trump republican? "But they didn't get rid of Trump, the dems stole it!"
How do you argue with that? You can keep pointing out the dangers of jaywalking to me as the axe murderer walks into your house if you like.
Whatever, its the Republicans that lead the dissatisfaction. "I can't have my way so I am unhappy!" Go in the corner and pout.
I actually think that's a valid theory on some of these polls - republicans are more likely to lie for their candidate. I believe democrats are more likely to be vocal about their dissatisfaction with Biden and democrat candidates than republicans are Trump or republican candidates. Like, even if republicans and democrats backed their respective candidates at the same rate, I believe some democrats would at least be honest and say "I'm not happy about the job he's doing" but vote for him, while a republican who had their crop rot thanks to Trump's tariffs will just take the government subsidy check and say "MAGA baby!"
Trump is so hated by independents and the left that I believe republicans reactively poll in his favor to combat the negativity.
Just a theory.
