Nah, there's no way he's doing this for the benefit of the Democrats or for anything other than elevating himself. He's someone who needs to be loved and seen as THE BEST, and if he's smart enough to be manipulating his public persona, then he's smart enough to see how badly he's damaging his 'brand'. And his brand is the most important thing in the whole world to him. I can't imagine he'd allow that to be tarnished in the service of someone else.
