Very smart decision to pump money in the Senate races, though I'd choose WI and perhaps IL instead of OH and IA...
Why WI? They usually have a knack for going hard-Democratic on Presidential years and Feingold is still well liked.
And Kirk's campaign is a joke.
Saving for LA Run-off would be more useful than IA though.
The race in WI is tightening. I agree about IL, but even there it'd be better spent than in IA or OH -- though even better would be not investing it in any of IL/IA/OH but using it in the other swing states.
