Make it clear to all your Republican friends that it's Ron Paul or bust! He's the only Republican candidate you'd vote for, and the only one who can bring a large number of voters into (or out of) their party. It doesn't matter if Ron Paul runs as an independent / third party or not, and it doesn't matter if you threaten to vote libertarian or not vote at all, just make it clear that's the only way they'd ever get your vote and that there are enough people like you to make a difference. The big government vote is split between Reps and Dems 50:50, so they shouldn't expect to win any election ever again (without cheating at least) without satisfying the Libertarian block, some of whom have voted Republican until now, and most never voted at all and never will - except for someone like Ron Paul!
And
sign this petition (and/or another one like it) and spread it around Ron Paul supporters:
To: US Citizens
I swear by all I personally hold right and decent, I will only vote Republican in the 2008 election if Ron Paul is on the Republican ballot.
Sincerely,
The Undersigned
Pure and simple. If you sign one Ron Paul petition this election season, this should be it. Though I'm only endorsing the idea of the petition, not this particular online method - an offline petition that can't be cheated would work best, especially since there are enough energetic Ron Paul supporters to take the clipboards out onto college campuses and other public places. And it's not just for Republicans - it's for any people who'd vote for Ron Paul (over Obama Clinton) if he's nominated and definitely won't vote for Rudy McRomneyson.
Remember how close the past two elections were! If we could get a hundred thousand signers on a petition like that, the GOP establishment would at least start showing Ron Paul's campaign some respect! A few hundred thousand more, and they'd be gettin' mighty scared then! And if we could get a million plus signatures - they'd outright piss their pants!
Remember, they believe in mainstream polls, that there are a million Ron Paul supporters tops total in the whole country - if more people than that sign this petition, their bubble will finally burst and the self-fulfilling prophecy will be defeated!
