Former Gov. Jeb Bush has quickly acquired a Twitter following of 1,699 (and counting) without a single tweet. Will being followed by Bush become the new status symbol for political junkies?

Of course, the Twitter account will spur a new round of speculation about whether he's angling for the White House in 2012, since tweeting is becoming as essential to campaigns as, well, fundraising.
