One is a poor candidate, the other is a complete disaster, as choices go there is no choice, good, bad, or indifferent...Akin or bust. But to the point made by Alan, it is up to MO, and that state is too squishy to predict an outcome, IIRC St.Louis is always one of those places where we always see nefarious efforts by libiots in Presidential election years, so both the POTUS and Senate races could be schizophrenic in outcomes.
