Not completely but Obama's approvals sure haven't taken a hit. The jobs report really gives Obama more ammo for the next debate and took away one of Romney's favorite lines. Nate Silver might be proven correct when he said Romney's base strategy had a ceiling around 48.7%.
I don't think his approvals would take a hit... just his support in the election. His approvals were already under 50%.
And the jobs number, okay, he may bring that out, but Romney can still hit him on the labor force shrinking, the fact that the job numbers have been declining since this summer, the fact that most of those jobs are part-time, our GDP is growing at a measly 1.3%... so they really are not much "ammo." That's the problem - Obama has little to run on.
What he has to do in the debate is call Romney out on some of the inaccurate things he says, which he utterly failed to do in the first debate, and hope it sticks. He really can't run on how great things are, because they aren't, even if it isn't totally his fault that the US is still struggling. He can take credit for our recovery from the great recession, but that may not make much headway with independents. He will have to paint Romney as dishonest and unable to handle the job to win the debate.
