No, but they must have a realistic chance to win. Akin no longer has that, therefore he needs to go. Simple as that. There is no use in sticking with a candidate who can't get elected when there is still avenues to replace him. There are plenty of other quality, pro-life candidates that can run instead of Akin and give us a realistic chance of taking this senate seat.
He is conservative through and through. Missourians will decide, not the drive-by media. Why would an incoherent comment change anyone’s mind to not vote for Akin and for the hated McCaskill who is joined at the hip with the weakest, worst President since before Carter?
