For the Democrats, all eyes are on Clinton, the secretary of state who professes no interest but would have a clear advantage if she runs for the nomination that eluded her in 2008. Cuomo, too, is being talked about heavily in Democratic circles.

Maryland’s Martin O’Malley appears to be laying groundwork and snagged a plumb gig in September, as the guest of Iowa Sen. Tom Harkin at his annual steak-fry fundraiser in the state that traditionally holds the kick-off caucuses. Other governors who may weigh bids: Colorado’s John Hickenlooper, Massachusetts’ Deval Patrick and Montana’s Brian Schweitzer.

Keep an eye, too, on mayors like Antonio Villaraigosa of Los Angeles, who co-chaired the Democratic convention and headlined the Iowa Democratic Party’s annual fall fundraising dinner in Des Moines last month, following a long line of would-be presidential candidates. And another potential: mayor Julian Castro of San Antonio, who delivered the keynote address.
