But McCain supporters make up for their small numbers with their ferocity.

I remember Clinton drawing a huge crowd in St. Louis in 1992. I stood on the steps to the library to watch him address the crowd. I had a megaphone since I was there to protest with ACT UP and a Secret Service agent walked up to me and politely asked me not to yell through it in the direction of the candidate since it could contain a gun. He was very nice about suggesting that I aim the megaphone perpendicular to the candidate so I could still be heard, but not be a security threat. I did as he asked.

And when I jumped down from the ledge that he and I were standing on, he held the megaphone for me so I could jump down easier. I've always remembered him since I never imagined the Secret Service agents to be so friendly. A couple of years later, I saw him again on TV walking beside President Clinton.

100,000 people!

Hmm...that's almost half the crowd he drew for his Berlin rally ;)

True, but it's bigger than any crowd he's drawn in the US (in Portland this spring or at his acceptance speech in Denver).

I should also point out that McCain held a rally in a suburb of St. Louis today; the St. Louis Post-Dispatch reports that it drew three thousand people. Compare and contrast.
