Unfortunately for Romney, the unfavorable/favorable numbers for both candidates stayed the same. What some Romney supporters are missing is that some in the poll being honest about the debate outcome does not necessarily equal a whole lot of change in opinion. Much of the vote is locked in right now.
This is the key question: What actual effect will it have on the numbers? The key determinative of that is what kind of sustainable momentum this creates for Romney to counteract the narrative of his being a near-sure loser in November. The jobs report may have an effect here. If the numbers are perceived as good for Obama, that will likely staunch any serious effect on the numbers. If the numbers are poor or even just middling, that may very well add fuel to the spark Romney lit last night.
Regardless it seems Romney accomplished mission #1: Proved that at least for now, the race isn't over yet. Obama must be kicking himself this morning; all he needed was a perceived tie and the election would've been essentially over as of this morning barring mega-gaffe/crisis/deus ex machina.
