There are new developments in the race for the U.S. Senate seat in New Hampshire being vacated by the retiring Jeanne Shaheen.

Former Senator John Sununu entered the race Wednesday. That means former Massachusetts Senator Scott Brown won't have the Republican primary to himself. In fact, recent polling suggests Sununu could be Brown's worst nightmare.

A UNH Survey Center/Granite State poll shows Sununu crushing Brown by 23 points among likely primary voters. Perhaps it's more recognition of the famous family name than anything else, but Sununu, brother of former governor Chris Sununu, has a solid 50 percent favorable rating among Republicans, while Brown, the state party's 2014 senatorial nominee, draws a measly 30 percent.
