Cruz or Walker. No way I'm supporting a guy that in the past has supported both Hillary and Obama. That is way beyond even worst of the other Republican candidates. He has in the past supported illegal immigrants. Just because he is riding the anti-immigrant wave today doesn't mean I could trust him. A skunk who has it's white stripe dyed black is still a skunk.
On the other hand painting a white stripe down a black cat's back don't make the cat a skunk Pepi.
