My "logic" says Ron Paul ran a very long campaign and was never a viable candidate. He couldn't raise the money or garner the votes necessary to win. He did not fare well in debates. He doesn't have the party loyalty necessary to convince enough members to vote for him. He doesn't have the charisma. There is no way he comes out of the Republican primary.
Unfortunately, a candidate needs more than good ideas, a solid moral compass, and great intellect (all of which Ron Paul has). It's a beauty contest that requires an obscene amount of money.
I like him, but anyone who believes he can win is dreaming IMO.
