If Sarah Palin is the muse and "Mama Grizzly" of the tea party movement, Sen. Jim DeMint, R-S.C., arguably is its father figure in official Washington, D.C., having proved to be a powerful influence with his endorsements throughout the GOP primaries. In a triumphant commentary Sunday in the Washington Post, DeMint declared President Obama's honeymoon over and promised Democrats a "heartbreaker election" on Nov. 2. "Thanks to the grass roots, Republicans have a slate of candidates who believe in constitutional, limited government," he wrote. "We will balance the budget, repeal the unconstitutional health care takeover, create a predictable tax and regulatory environment in which businesses can create jobs, and restore a sense of fairness to the economy." Of course, with the competence of some of the tea party victors still in question, their electability will remain in doubt until election night. Some observers believe DeMint is hurting his party’s chances of retaking the Senate.
