You are confusing predictions with actions. Nothing we say or do here will make a damn bit of difference as to whether Trump wins or loses the election, so trying to blame us if he loses isn't going to work.
And I think that you're missing the point. What most of us are feeling here is an incredibly deep sense of frustration at Trump. I think most of us have rather desperately wished he'd pull his head out of his a**, run an intelligent campaign, and not say crap that makes supporting him feel so damn dirty. But he just can't stop being who/what he is. Every single time I start thinking that maybe I could hold my nose and vote for the guy a third time, he says or does something that makes me think "f*** this guy. He's a damn idiot, and I will not vote for an idiot yet again."
The things that Trump proposes and says that makes everybody outside the MAGA bubble go “huh?” inside the bubble, they see as great strategy.
Now that they see a campaign in decline, after months of telling us that Trump doesn’t need the votes of conservatives, they are now reduced to questioning our ideology and patriotism because we will not vote for the guy. They dismissed all polling and evidence of Trump’s deep unpopularity with the public as fake. The left-wing strategy of promoting Trump endorsed candidates in 2022 in their primary so that they could go on and lose in the general election was a very big risk, considering Joe Biden’s unpopularity at the time, but it worked.
Maybe it’s just one of those things. In 2016, Hillary Clinton was the stale candidate and Trump was the new exciting shiny object. Now Trump is the stale candidate and Kamala Harris is the shiny new object.
Maybe the Republicans will get lucky and find another new shiny object for the voters in 2028
Trump is the oldest candidate to run for president. That also has to be in voters’s minds more so after seeing how quickly Biden declined in four years.
