I'm leaning between Cruz and Walker, but there are things I like about Rand Paul. The problem is if one of the better candidates stumble, we need someone better than Bush who is the worst of all choices. By tearing down the other candidates, it is more likely we'll get Bush by default just like what happened in 2012 with Romney.
The circular firing squad kills us every time, and Bush benefits from it.
There is no circular firing squad involved, conservatives oppose Rand Paul.
The only people who want Rand Paul in, are the ones who support him.
