What internals do you have issue with?
According to the poll, Moderates voters preferred McCaskill 63-22, yet the Very Liberal preferred her by only a 58-34 margin.
I don’t find this believable. There is no way on election day, 34% of the very liberal voters in MO vote for Akin. Either the got a weird sampling, or the Very Liberal voters were purposely distorting their response to prop up Akin until he can no longer drop out.
