One sliver of possible Democratic benefit from Obama's loss

Before President Obama's loss of the first presidential debate--a loss purely the product of his underestimating his opposition and the importance of the debate (he should have taken it as a given that Mitt Romney would be aggressive and lie prodigiously)--Romney's billionaire backers were about to pull their money from his campaign and direct it towards Senate races across the country. Now they're not--big money is sticking with Romney. So whether Romney's current advantage maintains through the election, Democrats may have a better chance of hanging on to the Senate--which is crucial, from the viewpoints of both parties.
