In a new television ad, Republican presidential candidate Mitt Romney says Indiana state Treasurer Richard Mourdock will be the needed vote in the Senate to repeal President Obama's health care law.The 30-second spot features Romney telling Hoosiers that Mourdock worked with outgoing Gov. Mitch Daniels to "balance the budget" and "make government more accountable" adding that his election will keep the Democratic agenda at bay. Romney has pledged that eliminating the Affordable Care Act will be one of his first acts if elected president, and the ad anticipates the Senate margin will be close."As Senator, Richard will be the 51st vote to repeal and replace government-run healthcare," says Romney.Check it out:With two weeks before Election Day, observers point out that Romney's ad could be the needed boost. It does not mention Mourdock's Tea Party support and instead highlights his cooperation with other public officials.For months, Mourdock's opponent, Democratic Congressman Joe Donnelly, has been pummeling him for comments showing a lack of compromise.Donnelly has also pulled out some big names in recent weeks to attract moderates. He recently held an event in Indianapolis with former President Bill Clinton as he continues to reach out to GOP voters who were supporters of Sen. Dick Lugar, whom Mourdock defeated in the spring primary.On Monday, Mourdock also plans to hold a fundraiser hosted by Senate Republican Leader Mitch McConnell, R-Ky., where the two will watch the final presidential debate.Several GOP Senators have visited Indiana in the past month, including Sen. John McCain, R-Az., and Sen. Lindsey Graham, R-SC, but Lugar has said he will not campaign for his former rival.
