In my experience, Paultards don’t have staying power. I attribute Paul’s showing not to crafty supporters, but to Romney-fatigued party regulars just backing away. I’m guessing the off-year caucuses in 2014 (yes, there are caucuses in Iowa in non-presidential election years) will be ripe for a takeover by Tea Party/social conservatives.
In even large Iowa precincts, a group of ten people (sometimes less) who plan ahead can pretty much take over a caucus. Find local friends and plan ahead.
Iowa’s Republican establishment has gone from domination by people who care exclusively about abortion who, after the court decision, added gay marriage to their litmus test... to being taken over by Paulbots that are already turning-off donors, drying up the money spigot coming into the state party... a finance guy that was slated to stay on thru the state convention recently quit. It’s not going to get better any time soon.
