you need to first vote, then go back to your polling place just before the polls close and let the poll workers know you are there for the Precint meeting which takes place immediately after the polls close. The people at the meeting elect a Precint chairman and sign up to be delegates at the County convention. Do not tell anyone who you support at this point. You should know who your fellow RP people are before the meeting, by working with the Campaign and local meet-ups. If you really want to be a State level delegate you need to get in tight with your County GOP officials, by volunteering to be on a committee or work a polling place or join and participate in GOP clubs, fundraisers etc. It really is a game of WHO you know, so my advice is to contact your local GOP now and start getting involved. The county convention elects delegates to the State convention based on the recommendation of a committee of die hard local GOP people who all know each other. If you can't weasel your way onto that committee be sure you get to know a couple of people on there who will support you. They make up their list after the election and before the County convention. That list is ramrodded through at the County convention. Now the fun part... you can, if you have enough RP people at the County convention, take over the floor and control the meeting by electing a new chairman and sending all RP folks to the State convention, but this is difficult to do. The mere attempt to do this will cause serious kiniption fits amongst the leadership but what the hell, these kinds of futile gestures (combined with some really good floor speeches) are just what is needed to shake some sense into some of these complacent FOX News zombies. And you never know you may succeed, so bring every RP supporter you can to the precinct meeting and overwhelm the GOP at every level.
One last thing... Look up what happened in Nueces County in 2008 and prepare, prepare, prepare. GOOD LUCK I hope to see you at the State Convention.
