The better things are for him politically, then better chance Trump isn't able to come back. If that means not being a full globalist then so be it.No guarantee Biden wins if gas prices today are low either. Again, its a bad signal to the rest of the world especially if your claim to fame is being a protector of democracy across the world.
Not banning imports also signals to Putin that you can't live without his resources. There's no power in that.
The entire Republican party is still bending the knee to Trump and its a cult of personality. The nomination is his and voters are simple and will think with their pockets. The economy did well under Trump pre covid. Record inflation and high gas prices under Biden. The choice is easy for simple minded voters like thatWhile Biden is no guarantee, there is no guarantee even for Trump to win the Primaries. He has been banned from Twitter, which benefited him alot along with tons of Free Media coverage for his antics. However in his latest public appearances, he has tried to seem Presidential; toning down his volume a bit. Not to mention a ton of his handpicked Candidates lost local elections last year.
He still has his followers, but really with Trump not having any social platform, along with now Russian money frozen; he really is going to hard time winning.
