As I said at the time...I thought Akin should leave the race, but I didn't think the party should try to make him leave...especially when they had no leverage to force him to do anything(The Packers learned the same lesson in 2008 with Brett Farve). This really is a difficult call. Everybody with an elected (R) behind his or her name begged Akin to leave. He didn't. RNC Chair Reince Preibus made it clear the party would NEVER support Akin.
So here's the question; what would be worse, giving Akin support when the whole party from the top down said his words were indefensible, or risk losing the Senate by the single seat Akin is seeking? To suddenly start supporting him again would give the left an opportunity to fire up the "War on Women" machine again. But that didn't work all that well the first time. And Republicans don't have a seat to play with. And the reality is it would be 100% hypocrtical to reverse course on this.
As I said, it wasn't the party's place to tell him to go.
