Zeb is right here, John.
As I've mentioned on a few threads, the GOP Candidates are sort of 1) playing to their strengths 2) "playing nice" with each other and 3) focusing on the President. (As it probably SHOULD be at this point).
But the Primaries are a brutal process, where the candidates will HAVE to begin to differentiate themselves from each other.
I'm no Paul expert...but supposedly he has said and written things that will be exposed and ridiculed by the other candidates as things heat up.
His supposed grasp of economics and the Federal Reserve simply won't be enough to save him from the bombs that will be thrown his way.
