Former Massachusetts Sen. Scott Brown has been spending quite a bit of time in New Hampshire testing the waters for a possible U.S. Senate run there next year, but the Granite State is also a place where presidential contenders frequent and Brown is again not ruling out a 2016 run.

"I don't think I ever said I was thinking about running for president," Brown told reporters at a stop in Londonderry, N.H., according to the Stoneham Patch. He then added "I don't think anything's off the table at this point."

Brown first floated the idea of a possible 2016 presidential bid in August, even stopping at the Iowa State Fair, a rite of passage for any presidential contender.

At the Iowa State Fair, he told supporters he was "exploring a possible run" and indicated to reporters that he's interested in seeing how voters in Iowa feel about him.

"I'm going to be coming out more often to try to determine whether there's an interest in my brand of leadership and Republicanism," Brown told the Des Moines Register on that August trip.

When asked last week about his possible aspirations to rejoin the Senate, but this time from New Hampshire, Brown would only say in an e mail to ABC News, "Nothing has changed. I'm all set. Thanks for checking."

In Londonderry, Brown slipped in a shot at his former rival, Elizabeth Warren who announced last week that she won't run for president in 2016.

"Listen, you have to have a record first," Brown said. "I think you actually have to go and pass legislation and have experience to be president. I think that's critically important."

Brown added, "That's a personal decision she made."

Brown lost to Warren last year by almost eight points.
