With Rick Santorum abandoning his GOP bid on April 10, Mitt Romney has become the presumptive Republican presidential nominee. Recent polls show that Romney and President Obama are neck in neck in the eyes of the nation. But does Romney have a secret weapon?

It's becoming more apparent that Mitt Romney's wife, Ann Romney is becoming an "effective political weapon." Referred to Romney as his "sweetheart," the U.S. is only just starting to take notice to how powerful Ann Romney might be in the upcoming election. A poll released by Quinnipiac University revealed that 64 percent of registered voters "don't know enough about her to form an opinion," reports the Associated Press.  The same poll found that 25 percent view her favorably, while 9 percent do not.

"Ann Romney is clearly an asset to her husband's campaign," said Democratic strategist Karen Finney to the Associated Press. "But while she may help voters to take a look, ultimately Mitt Romney has to seal the deal...not even her excellent campaign skills can make up for whatever concerns voters may have about whether or not he'd be a good president."
