The republican party needs this more than Trump. The GOP already has a big problems with their own voters. They need to prove that they can actually function as a legitimate political party and generate majorities and get results.
Trump will get control of The DOJ and FBI one way or the other. He will be The President after all.
Part of me hopes that they do try to play games and be obstructionists. The GOP will only destroy themselves and they will not be missed!
What do you mean by "this"? Gaetz as Attorney General? Because no, the GOP does not need Gaetz as AG - at all. And neither does Trump even if that is what he believes. He and the GOP both would be far better off with someone else.
Gaetz is great at making a lot of noise but accomplishing nothing. And putting him in charge of a massive organization about which he knows nothing is guaranteed to produce the same non-results.
