Three writers at National Review give their opinions on voting for him, or not. I hope these links work. They may be subscriber-only.
Of the three, I'm most nearly in agreement with Cooke. However, unless something dramatic happens between now and November 3--and I can't imagine what that could be--I'm going to "vote for Trump." That is, I'm going to vote against Biden/Harris.
It's a Scylla and Charybdis choice. As I may have said here in a comment a while back, I had been thinking of that analogy, but in a mistaken way. I was thinking that Ulysses somehow steered between them, and that our position is worse because we have to choose one or the other. But I was misremembering. Ulysses chose to steer closer to Scylla (monster), who would inevitably eat some of his sailors, rather than to Charybdis (whirlpool), which would result in the loss of the entire ship.
So the analogy is actually precise. I think the damage that will almost inevitably be done by Trump is less than that which the Democrats actively intend.
It's not that I think Trump is a better man than Biden (I think they're both pretty sorry, actually). My great-grandfather was active in Pennsylvania politics as a Democrat, and his daughter, my great-aunt Ann, once told me that he advised her to forget the conventional counsel that one should vote for the man and not the party. On the contrary, he said, voting for (or against) the party is more important, because individual politicians come and go but the party persists and, at least in theory, shares your political principles, at least the most important ones. Here again it's a question of voting against: I don't want the Republican Party's principles, such as they are (whatever they are), to prevail, but I believe the Democrats as a party no longer believe in our form of government, but want to "fundamentally transform" it. I don't. That's a bigger problem and a deeper disagreement than anything involving specific policies.
As Cooke says:
If the Democrats were sensible, I would likely sit this one out. But the Democrats are not sensible. The Democrats are threatening to blow up the American constitutional order in ways that would make President Trump’s execrable excesses seem quaint.
