ST. LOUIS – Rep. Todd Akin renewed his vow to carry on with his embattled Senate campaign Tuesday, even as a key deadline loomed to withdraw from the race over his comments that women’s bodies can prevent pregnancies in cases of “legitimate rape.”

Akin, who has been frantically trying to salvage his once-promising bid against incumbent Democrat Claire McCaskill, insisted the uproar surrounding his remarks was an overreaction to misspeaking “one word in one sentence on one day.”

For the second time in two days, Akin went on the radio show hosted by former Republican presidential candidate Mike Huckabee to say he planned to stay in the race, despite constant urging from prominent members of his own party to step aside.
