Another Senate GOP seat in play as incumbent draws credible challenger.

Former New Hampshire Governor, Jeanne Shaheen, will be a candidate for the U.S. Senate in 2008, as she is set to challenge GOP Senator, John Sununu, who narrowly defeated her by 4% points.

So far the GOP seats are up for grabs with STRONG Democratic contenders, but EVERYTHING will depend on how the political climate in 2008 shakes out with Iraq, etc. .
