Rush -- along with just about every other conservative in the country -- was screwed either way. Support Trump, and conservatives will say he's sold out conservatism. Support Cruz, and the populists will say he's in thrall to the GOP-E. It's a no win situation.
And in fairness to Rush, he hasn't trashed Trump. He says Cruz is the most conservative, and if that's the most important thing to you, vote for him. Trump is the nationalist/populist, and if the most important thing to you is to destroy the elites, then vote for him. Not really sure how anyone could quarrel with that.
Always an exciting prospect. Usually does not end well. Wait. What?
Because Trump?
Never mind.
That is a fair analysis. I may be wrong. But i will never listen to that Ba$tard again. Enjoy.
