Former Massachusetts Republican Sen. Scott Brown is reportedly moving to New Hampshire.  Cue speculation about another run for the U.S. Senate:

The move will fuel speculation that Brown intends to challenge New Hampshire’s Democratic U.S. Senator Jeanne Shaheen, who is seeking re-election next year. Brown lost his Massachusetts Senate seat to Democrat Elizabeth Warren in 2012.

Republicans need a net gain of six seats in the 2014 midterms to take control of the Senate. The party already has a majority in the U.S. House.

A former New Hampshire governor, Shaheen, 66, was elected in 2008 with 52 percent of the vote in a three-way race, according to the New Hampshire Secretary of State’s office data. Two Republicans, former state Senator Jim Rubens and activist Karen Testerman, already have announced intentions to challenge Shaheen.
