Will Last Night's Debate Change the Momentum?

In Colorado this morning, President Obama gave an energetic stump speech, but even Democrats agree he was uninspired in last night's debate compared to Mitt Romney. Republicans are cheering Romney's aggressive performance, and both sides are wondering why the President failed to seize several obvious opportunities. Was he out of practice? Was it part of his campaign strategy? Will a different Obama turn up the next time around? In the meantime, can Romney use positive news coverage to establish a lead among potential American voters?
