Not sure if I am misunderstanding you here, but the republicans absolutely do want Trump. They wanted him in 2016, in 2020, and now again in 2024. If they didn’t want him, they wouldn’t be on the verge of making him their nominee.
Perhaps what you mean is that deep down, establishment republicans don’t want him. Guys like McConnell. You might be right, but almost all of those people are too chicken shit to do anything about it. And the ones who aren’t chicken shit - Cheney, Romney, Kinzinger - have been driven out of the party (because the party, on the whole, worships Trump).
The sad truth is that today’s Republican Party is comprised largely of ultra conservative religious folks and dim-witted morons. These people are blinded by their love of “God,” their hatred of anyone in the middle/left, and their low IQs. This makes them especially susceptible to being fooled by Trump.
