Those who aren't involved as the OP's brother obviously is, are the ones who wail about 'no vote fraud', 'you're conspiracy nuts', 'makes us look like sore losers' and 'I need hard evidence'.
Funny shit, that.
The 1st meeting you attend as a delegate, you'll see the old guard and how they have operated with a free hand for decades, hidden in plain sight.
As soon as they feel the least bit threatened in that regard, and especially if they see you have a majority or even a possible majority, they'll howl like the witch after Dorothy splashed the bucket of water on her. Then, watch the machinations begin. Rules changes with no prior warning, violations of procedure (yes, knowing Roberts Rules Of Order is a MUST), changes in delegate elections to state and national, vote count fraud and worse.
In the '08 cycle, at my state convention, I met and spoke with Libby Dole, Mike Huckabee, my state AG and state gubernatorial hopeful from my county... first. It was they who introduced me to my county chair and her gaggle. They (much unlike the many conspiracy squashers on this forum) not only didn't deny it happens, they explained why and how it happens.
To those who live in Wonderland on these issues, I used to feel sympathy to your ignorance, but these days it's just plain intolerable BS. Get out there, become a delegate, grab up RROO and READ IT, go straight to the top and work your way down. Matter. Less BS and more informed action.
By the time you get your taped conversation and hold a public trial for 7000 pages in this forum to vet the recording, the election will be over.
