Sorry to spoil your generality. Trump is a populist, not a conservative. He holds some conservative views on some things, but the reason he gets my support is that he stands up to the liberal media and proposes politically incorrect policies. Cruz has a strong conservative record and would be great. But were it not for Trump the media would have destroyed Cruz by now.
They are using Trump in an attempt to destroy Cruz now.
Trump is a populist/moderate/liberal masquerading as a Conservative which makes him a fake. Trump spends more time attacking Conservatives than he does attacking democrats.
