FiveThirtyEight: Missouri Still Democrats' Top Pickup Opportunity in 2010

FiveThirtyEight's Nate Silver:

3. Missouri (R-Open) -- Robin Carnahan's polling has been very stable, continuing to show her with a very slight lead. That's probably because her opponent, Roy Blunt, is a rather vocal member of the sitting Republican Congress, which is losing popularity just as quickly as the Democrats in Congress are. He's the wrong candidate for this type of cycle.
