Which tells me that you are NOT involved with your local GOP.
So you imagine that they are all some BIG, BAD, BOGEYMEN.
Most of the GOP -- like in my state of Wisconsin -- do NOT want or like McCain, really don't like Romney or Huckabee either -- they ONLY reason they do not support Ron Paul is because many of them are still "attached" to Bush and their insane Iraq War -- they rest just don't know WHAT to think.
THE "support" for that war WILL CHANGE -- as soon as a DEMOCRAT takes power and "owns" the Iraq War. If they are true Neo-cons they will leave the party and go for HRC (like Ann Coulter is doing) or they will stay home (like Rush Limbaugh).
The only local Republicans I have met who actually SUPPORT John McCain are essentially the really OLD folks who were (strangely enough) in the MINORITY back in 2000 in supporting McCain against the BUSHCO machine. Within a few years they will be either inactive, or quite frankly, dead.
Currently the rest of the party feels like they are having McCain "shoved" down their throats by the MEDIA and subsequently a few people in positions of power (who themselves do not LIKE McCain but feel they HAVE TO push for members to support "whoever" the primaries "choose") -- and the REASON they are pushing that is because otherwise -- like you, they will NOT vote for the Republican candidate. (And as a minority party losing ground every day, they need EVERY VOTE).
We CAN take over the Republican Party... but only if we stay ACTIVE ALL ALONG THE WAY to the next election.
You can't play "groundhog" and just stick your head up once every four (or worse eight) years and expect to make any solid difference. (That is one of the MAIN problems with all 3rd parties -- since they have few or no elected officials, they "disappear" between election cycles, lose every inch of ground they gained, and have to work hard to reclaim it again.)
I normally went for the GOP before RP showed me the truth. I hated the democrats, and still do hate those communists. And I still would go for the GOP vs the illegal, welfare loving commucrats.
But RP running independent is far more productive than him not running at all (If he doesn't get the republican nomination).
And most of the GOP here in Florida would take Mitt over Ron Paul anyday. Sadly many have become brainwashed to think that preemptive war is effective and a good thing.
