John McCain Is Congress's Twitter King

John McCain is leading the charge of tweeting lawmakers, with 46 times more Twitter followers—a cool 1.7 million—than his nearest competitor, Missouri Democrat Sen. Claire McCaskill. McCain’s popularity also illustrates Republicans’ quick embrace of the social network; twice as many of them tweet, compared to Democrats. “I love it; it’s so interactive,” McCain tells Bloomberg.

To be fair, McCain has a little help: He often has a staffer draft his pithy dispatches. “She’s so much faster than I am,” he reasons, though he does “scan all the time and compose tweets.” GOP Rep. Darrell Issa appears to take the Capitol Hill record for loquaciousness, with around 4 tweets a day.
