Clod Akin did. As did O'Donnell, Angle, Miller, Buck, Hoffman ...
And prideful selfish Akin is dragging the ENTIRE GOP (including conservatives) down with him! Until Akin withdraws, the DNC/MSM marxist media complex will use this in every race twisting it in their pathetic claim that it is a part of a Republican pattern in their 'war on women'.
Nobody outside of their local states gave a damn about O'Donnell, or Angle, or Milelr, or Buck, or Hoffman. They were all localized incidents that the media tried to make national, but at the end of the day no a single voter in OH or NJ or MN cared about them. Akin is different as he's not just quirky he's a liability to all good social conservatives.
