I think part of the disconnect we're having is that I'm naturally more conservative than you, and there are a couple of things I take for granted.. (1) there's something fundamentally broken in the West (2) as much of a practiced politician Trump is, he's not a part of the establishment..
I might be wrong, but I think you underestimate how dissatisfied those more conservative than you are with the state of the world. This manifests itself in terms of cultural issues (no need for us to go there), economic issues (inflation), geopolitical issues (the wars and China). In comparison to many conservatives I'm considerably more... centred.. than others. You only have to look at some of the conversations
@britbox and I have (the erosion of our freedoms, the tyranny of the State). I spent a weekend at my sister's a few weeks ago... and I was disheartened when she told me that on reflection.. she's more inclined towards hoping that Trump wins than Biden. Her view is that on balance Biden might be the greater evil. I can't tell you how common that view is. I hate it! Hate it hate it hate it! And I spent a lot of time trying to argue to her that the immediate threat is whether democracy itself continues to exist. But there are so so many people who've seen enough, and are fed up. They don't think Trump is good, but they are so dissatisfied with the direction of things, it distracts them from Trump. When I express my fears about Trump, please understand it in the context that I recognize the utter disgust half the voting population has at the moment. It is my humble opinion that either you're not aware of this or you dismiss it. This is understandable if you're not exposed to a more conservative perspective.
The point is that Biden is the avatar of the establishment, and to a lot of people he
will be associated with the chaos of these campus protests. I'm not saying it's right. I'm frustrated by it, but I recognize where the blame will go. It doesn't matter that the US isn't directly involved. US dollars are being spent on this, and not on things that have a more direct benefit to US citizens. Or for some of us more fiscally conservative people it's money that doesn't exist that shouldn't be spent.
I hope the abortion issue, the democratic threat, the relative outperformance of the US economy, the relatively drama free Biden Administration will enable Biden to win as an incumbent. That's what history tells us should happen. But I know, I see, I recognize that there is a terrible terrible dissatisfaction that for some reason those on the Democratic side seem largely oblivious to. These things might seem like a 'side-bar'... but I
promise you... if Trump wasn't the psycho he is, there's a pent up backlash that's bubbling... we want our world back, our freedom's. We don't want the State to tell us how to live...
