I believe you are correct. Huck is just running interference for Bush, so there’s no need for Huck to join this Iowa GOP fundraiser. But he’ll spend Bush money on the Iowa Caucuses, I’ll bet.
I have no doubt that Huck entered the race with the sole purpose of injuring Cruz and Walker, both with evangelical backgrounds.
I think the dumbass thought he had a chance to pick up the pieces and get the nomination after the bloodletting. All any real conservative or libertarian/conservative would have to do to beat him is show that clip on youtube of him demanding in a speech before the Arkansas legislature that they raise taxes.
