Depends on what your standards are. For a fringe candidate that was never going to be acceptable to a plurality of GOP voters, he's done pretty well. If you mean a candidate looking to actually win the nomination, of course he's gotten thrashed.
As an ideological candidate looking to pull the more mainstream guys towards his positions? Haven't noticed Romney or anyone feeling pressured by Paul's stances on civil liberties, foreign policy, or the drug war. There does seem to be more general paranoia about the Fed from the right than I can remember, but I don't think that's going to translate into anything serious. Maybe I missed something. benji?
Anyways, I'm sure lots of Paul supporters (especially the young, libbie-come-lately types) are all wound up about him being denied coverage by the military-industrial-media-fluoridation complex, but he's been treated fine for a guy who never was going to win, and who failed to deal with adverse press when the newsletters were brought up.
