Despite having a terrible political name, Jeb Bush (the Jeb, not the Bush) is probably the best hope for the GOP in 2008. Dick Morris thinks Condi is the only one who could beat Hillary, but I'm with Matt Towery who thinks Jeb has all the tools. Check out his column on the superb job Jeb has done as Florida's governor.
For the record, I'd be freakishly pleased to see Condi run, too. I just don't buy the idea that Americans wouldn't elect three Bushes to the Presidency. People like stability and they like brand names. Bush has become a pretty good brand name in politics. It ain't Reagan, but it's pretty good.
