McMahon's Obama ad irks some GOP supporters Linda McMahon's U.S. Senate campaign will not cancel a television commercial that has angered some of her GOP base by appealing to supporters of President Barack Obama. Launched over the weekend, the television spot features a handful of voters identified only by first name who said they are splitting their ticket, voting to re-elect Obama, a Democrat, to the White House but sending McMahon, the Republican Party's nominee, to the Senate. The Obama ad has some complaining it appears McMahon has endorsed the president's re-election and thrown Republican nominee Mitt Romney under the bus. Tea party activist Bob MacGuffie said the spot is poorly executed, but he will still vote for McMahon and doubted the controversy will cost her GOP support.
