Talk about a summer blockbuster! In the spirit of Alien vs. Predator II, the U.S. Senate race in New Hampshire is gearing up to be a rematch of epic proportions.

In one corner: incumbent Republican Sen. John Sununu, who first arrived on the political scene after messily bursting out of his father's chest during a George H. W. Bush cabinet meeting in 1991.

And in the other: former New Hampshire Governor Jeanne Shaheen, a Democrat who has survived multiple gunshot wounds and a tank attack with little discomfort, although she did stain some carpets with her dark green blood.

Sununu and Shaheen last faced off in the 2002 Senate election, when the Republican won by very narrow 4% margin…

Polls showed the two New Hampshire political heavyweights neck and neck until Election Day. But in the end, Mr. Sununu appeared to pull out a decisive victory. With 96 percent of the precincts reporting, Mr. Sununu had 51 percent of the vote while Ms. Shaheen had 47 percent. At 10:30 p.m., Ms. Shaheen conceded the election.

As of today, Shaheen is leading in the polls and is favored to win in this increasingly Democratic state.

Although the sharp Republican downturn in the state boosted Shaheen to big leads in polls into the summer, Democratic officials approach the race with only cautious optimism — in part because the senator’s name is big in state politics.

"This time around, the mood is much more anti-Republican in New Hampshire, so [Sununu’s] going to have an extremely difficult time," said [Andrew Smith, director of the University of New Hampshire’s Survey Center.].

Meanwhile, on the House side of the Granite State, another exciting rematch is shaping up between Rep. Carol Shea-Porter (D-NH) and the man she defeated in 2008, former Rep. Jeb Bradley (R-NH).
