This is interesting: Former Sen. John Sununu (R), who has not declared he will run, leads Rep. Paul Hodes (D), who is running, in the race for retiring Sen. Judd Gregg's (R-N.H.) Senate seat in a new poll.

Sununu leads Hodes 46 percent to 41 percent, according to the Granite State Poll. Also notably, Gregg, if he decided to run, would beat Hodes by a 52 percent to 36 percent margin.

There was a plus or minus 4.4 percent margin of error in the poll.
