Well, that's impressive. Yesterday's McCain/Palin townhall was screened, and people had to register with their local GOP offices and pick up the tickets at the party headquarters for the event. This is, of course, the opposite of McCain's normal town hall strategy, where "anyone may wait in line on the day of the event and come in without an advanced invitation." Of course, McCain isn't scared of his ability to answer hard or unexpected questions. With 24 years of political experience, he's confident in his knowledge of public policy. Instead, he's scared for Sara Palin.
