Rick Santorum has some pent up issues with Jim DeMint.Just a few weeks before DeMint stood for re-election on South Carolina’s ballot, Rick Santorum showed up in DeMint’s neighborood to tell everyone Jim DeMint was wrong on earmarks. “Former U.S. Sen. Rick Santorum of Pennsylvania said the Constitution gives Congress control of the purse strings and that he supported earmarks for port deepening while a senator – the opposite of the position that DeMint is taking. But former U.S. House Speaker Newt Gingrich of Georgia said DeMint has shown “moral courage” in refusing to support any earmarks, including one that the State Ports Authority says is needed to study the deepening of Charleston Harbor.”Santorum went on John King USA on CNN tonight and again defended earmarks claiming “Jim DeMint did it too” without acknowledging DeMint repented and has since led the fight against earmarks. When asked about what he may or may not have said about black welfare recipients, Santorum defended himself by claiming he got earmarks for a black community in Pennsylvania.Get ready for conservatives to have to refight this critical fight against the gateway drug to big government spending.It’s not just Rick Santorum knocking Jim DeMint (!!!) when not hiding behind DeMint to claim tea party bona fides, Santorum is also going to have trouble in South Carolina because of his voting record. He opposed National Right to Work legislation.In the 104th Congress Sen. Santorum joined all Democrats and a minority of Republicans in voting to filibuster the bill S. 1788, the National Right to Work Act of 1995. (“On the Cloture Motion (motion to invoke cloture on motion to proceed to consider S.1788),” Senate Bill Clerk, Vote Number: 188, www.senate.gov, 7/10/1996)During that same congressional session, Santorum also voted to retain the 1930s-era Davis-Bacon Act that forces taxpayers to pay union wages in government-funded construction and gives Big Labor an unfair advantage over non-union companies and workers (“On the Motion to Table (motion to table Kennedy Amendment No. 4031 to S.Amdt. 4000 to S.Con.Res. 57),” Senate Bill Clerk, Vote Number: 134, www.senate.gov, 5/22/1996)Santorum supported Arlen Specter over Pat Toomey in 2004 helping Specter secure the nomination. Specter went on to cast the 60th vote for Obamacare and then lost, in 2010, to Pat Toomey. Toomey, now in the Senate, is con-sponsoring Jim DeMint’s National Right to Work legislation — the very legislation Rick Santorum filibustered.Santorum being on the wrong side of National Right to Work and Jim DeMint will do him no favors in South Carolina.
