St. Charles, Missouri (CNN) - The term "#Akin" was still trending on Twitter Tuesday, two days after the Missouri congressman committed a gaffe on rape. And Missouri voters were still reeling from what many viewed as an incendiary choice of words.

Republican Todd Akin had until 5 p.m. to decide whether he ought to remain in a U.S. Senate race. He has apologized for saying that a woman's body is capable of preventing pregnancy in cases of "legitimate rape." He asks for forgiveness in a new television ad.
