CBS/NYT poll: Romney up 3%

According to a CBS/New York Times poll, Mitt Romney is now leading Barack Obama, 46%-43%, among registered voters.

This means that the president's lead in the RCP average of polls has now shrunk to just 1.4%.

Some internals:

a. Barack Obama's favorable ratings aren't too mighty. He's only at 45%/45%. But that's still better than Mitt Romney, who's at 31%-38%. As you can see, there are still a lot of voters out there without a clear picture of Romney. That carries advantages and disadvantages for Romney.

On one hand, he has a chance to define himself. On the other hand, his opponent also has the chance to define him.

b. It's still the economy. 62% say the economy will most heavily determine their vote, while another 11% say the budget deficit. That means 73% will use some type of fiscal criteria. Not great for Obama.

c. Meanwhile, 51% say gay marriage shouldn't be legal, and only 41% say it should.

d. Obama's decision seems to be a net negative, so far. As in other polls, his gay marriage flip-flop makes more voters (26%) less likely to vote for him than more likely (13%).

And rather than being viewed as a moment of leadership, most view the decision cynically. 67% think he made the decision for "political reasons" and just 24% say he did it because he thought it was right.
