It can't be a very well thought-out plan if using Trump is essential to it. Desperate is more like it. Trump is the liability here. Bannon may be clever but Trump is not. Trump is a loose cannon who will eventually cross a line that will undermine his ability to implement his agenda (and Bannon's). In truth it is already happening. He is simply not a good leader, even for the right. 

Bannon is going for it in terms of trying to implement his nasty world view through Trump, I agree, but he's on the deck of a very leaky boat.
