Cory Booker became a national celebrity of sorts in 2002 when he nearly ousted Sharpe James in the race for Mayor of Newark. When he ran again four years later, he won 75% of the vote. Just 56% of New Jersey voters know him, but those who do like him: he has a 32%-7% favorable rating.
Booker insists he's not ready to leave Newark, but Democrats speculate that he would consider running for Governor if Jon Corzine doesn't — and there's considerable buzz that he could get tapped to become Corzine's candidate for Lt. Governor next year.
