So the 71% of the MO voters who voted against Obamacare will vote to reelect the senator who voted FOR Obamacare and does not want it repealed rather than for the candidate who voted AGAINST Obamacare and wants it repealed? For some verbal gaffe? I guess MO is going Obama.
I think that you may be assuming that voters are rational and think through how they vote. Many do no such thing, they vote on emotion and those emotion change like the wind. Claire is portraying Akin as a lunatic who will ruin their lives. The emotional ones are going to be very receptive to that argument.
