He can be anti establishment and still not alienate his base voters, at least for now. Telling people that he's in favor of tough spending cuts might be alright, but then the next question is what specific cuts? He can't just BS this question, so he has to start getting into the real stuff.
No one wants to hear about the tough decisions. If they did, we'd be talking about the Paul Ryan budget plan. Maybe some people would welcome his anti-establishment candor, but at this point, it would just give the others the chance to pile on.
Conservatives like budget cuts, in general, but no one wants their own stuff to be cut. The right things don't happen in politics because politicians are stupid, they don't happen because deep, tough cuts are really hard to get passed into law.
