Jeb would make a fine president, regardless of his name (even if it were, shudder, Clinton).
As of now, he's given no indication he intends to run in '08. If he changes his mind, he'll have my support. I think it's more likely he'll run at some later point.
"Jeb would make a fine president, regardless of his name"
If his last name were Smith, he would be the clear frontrunner for the GOP presidential nomination, if not W's runningmate in 2004. He's a solid conservative who is a policy wonk and an intellectual, yet has great popular appeal. He won reelection as Florida governor handily in 2002 in spite of being in the liberals' cross-hairs, and his presence on the ticket would just about guarantee Florida's 27 electoral votes for the GOP. It's really a shame that he would face such strong opposition to a presidential run to replace his brother in the White House.
