Shaheen set to take on Sununu again

John Sununu’s (R) seat in 2008.

“Jeanne Shaheen will be a great candidate and a great Senator,” said Democratic Senatorial Campaign Committee Chairman Charles SchumerCharles (Chuck) Ellis SchumerMJ Hegar announces Texas Senate bid Hillicon Valley: House Dems subpoena full Mueller report | DOJ pushes back at 'premature' subpoena | Dems reject offer to view report with fewer redactions | Trump camp runs Facebook ads about Mueller report | Uber gets B for self-driving cars Dem legal analyst says media 'overplayed' hand in Mueller coverage MORE (D-N.Y.). “We are excited that someone who represents the best of New Hampshire and American values is our candidate for the Senate.”

Shaheen’s entry sets up a likely rematch from the 2002 race, in which Sununu, then a congressman, narrowly defeated the three-term governor.

Shaheen has been at the top of national Democrats’ wish list but has said little about the race for months. Leaving her post as head of the Institute of Politics at Harvard University made the decision particularly tough.

The Institute of Politics on Friday announced her resignation, effective at the end of the day.

In recent months, Shaheen has polled as many as 28 points ahead of Sununu. The state underwent a massive shift toward the Democratic Party in the 2006 elections, and Sununu appeared vulnerable regardless of whether she entered the race.

Former state Democratic Party Chairwoman Kathy Sullivan, the spark behind an online Draft Shaheen movement, said she sent a message to the former governor Friday morning thanking her for getting in.

Sullivan said she would continue to do whatever she can to help Shaheen win next November. As for the rest of the Democratic field, Sullivan said it would be "up to them" to decide whether to stay in the race or clear the field for Shaheen.

"Now that Gov. Shaheen is in, it certainly does make it a different race than it was yesterday," Sullivan said.

Astronaut Jay Buckey (D) said early Friday morning that he would stay in the race, and Portsmouth Mayor Steve Marchand (D) has recently backed off a pledge to defer to Shaheen.

Marchand and another Democratic candidate, Katrina Swett, are expected to issue statements today.

John Warner (R).

 “With Jeanne Shaheen and Mark Warner announcing their candidacies in the last two days, our efforts to increase our majority in the Senate got a tremendous shot in the arm,” Schumer said.
