No, it didn't.Negativity Wins the Senate
Actually, it did. In the sense that the Republicans didn’t run on anything other than how bad it was to have voted 96%+ for Obama policies, which all Dem senators did. Since they ran on nothing else, the Republicans have a mandate to repeal ObamaCare, build Keystone XL, etc. That’s the only message the voters could have sent with the vote. If they wanted more cooperation with Obama, they could have voted for Democrat control of the House. They didn’t.
