Well, I don't know how New York works, but you need to show up at whatever Republican Party convention you can and get in on the voting, and if you can, get all the Ron Paul supporters you can possibly muster to come with you and be prepared to pay whatever fees are required to become delegates to the state convention. In Alaska we had to dish out $200 per person for this... the most willing people are the people who have already contributed money to the national campaign, so we contacted all of them first.
The national campaign paid for a couple people that couldn't afford it (coordinated with state HQ) but we mostly paid for ourselves and each other.
We were completely silent about this. This organization and planning was going on for some time, but I didn't even post on this forum because I didn't want it to get out to ANYONE, even as much as I wanted to suggest the other states do the same thing we were doing.
We showed up with no visible Ron Paul banners, stickers, pins, or anything. We didn't say a word about Ron Paul the entire convention. We acted like we didn't know each other. I think by the end of the convention, everyone had it figured out that there was a big ol' Ron Paul conspiracy in their midst, but by then it was too late.
