While he doesn't plan to join up with any of the 2008 presidential candidates, Clinton political adviser James Carville is giddy with anticipation. "We'll have more run in 2008 than we've ever had," he says. Carville has the primaries mapped out and predicts "larger than life" candidates will emerge. His Democrats: Sen. Hillary Rodham Clinton, Sen. Barack Obama, and former Vice President Al Gore. On the Republican side he sees Sen. John McCain, former New York City Mayor Rudy Giuliani, and former Speaker Newt Gingrich fighting for the nomination. And there's a "real, real, real" chance of a third-party move.
