Former Massachusetts Sen. Scott Brown compares the Republican Party's infighting to "dividing each other and fighting over the scraps when we actually could be uniting."
"What we are finding now is that it is not good to be a Republican," Scott told former Arkansas Gov. Mike Huckabee on Fox News Channel's "Huckabee."
"There's some sort of litmus test apparently that we all have to follow.
"There's got to be room for people like you, for people like me, for Rand Paul and Ted Cruz — and we then need to take those ideas and bring them forth to the American people. We need to move forward together.
Brown, 54, who lost his Senate seat to Democrat Elizabeth Warren last fall, is also a Fox contributor.
Both Paul, who represents Kentucky, and Cruz, who hails from Texas, have been criticized by other Republicans and other conservative groups for going against mainstream GOP ideas.
In fact, during the debate on a continuing resolution to finance the government, Cruz spoke against Obamacare for 21 hours and 19 minutes on the Senate floor. The opposition and the skirmish over extending the nation's debt ceiling led to a 16-day partial shutdown of the federal government in October that cost American taxpayers $1.4 billion.
Brown told Huckabee that during his nearly three years in the Senate, having been elected to complete the term of Sen. Edward Kennedy, both Republicans and Democrats "had to fight for my vote.
"I was the 41st or the 60th vote — and there were times when my own party was very critical, so I was battling on the left and the right," Brown added. "I said to myself that I was going to go down there and do what's right for the country first, and that's what I think more people need to do."
Earlier this month, Brown moved to New Hampshire, fueling speculation that he intends to challenge Democratic Sen. Jeanne Shaheen, who is seeking re-election next year.
He told Huckabee that his move was for "personal reasons," but attacked Shaheen for casting the deciding vote to approve Obamacare in 2010 and for being among six senators who wrote the Internal Revenue Service last year asking the agency to investigate conservative, tea party and religious groups in their applications for tax-exempt status.
"She rammed it through — and she voted for it, obviously — and she voted against every grandfathering amendment," Brown said, referring to Obamacare. "She's going to have to answer to somebody."
On Sunday, Brown predicted Republicans will take over the Senate in 2014, but was coy on whether he would be part of that takeover.
Appearing as a panelist on "Fox News Sunday," Brown shared some of his predictions for the coming year. Host Chris Wallace noted that Brown, a former GOP senator from Massachusetts, has sold his house in that state and is currently living in New Hampshire.
So, Wallace asked, would Brown be part of that predicted takeover by running for the Senate from his new home?
"I'll be making some obviously very important decisions in the near future, and I'm not going to do it today. So, let's move on," Brown responded, then turned to ask former Sen. Joe Lieberman, I-Conn., for his predictions.
"Wow! I guess I got told," Wallace laughed.
"I will not be seeking the Senate seat from New Hampshire," Lieberman jumped in.
"I'd vote for him," Brown said.
