Here is what it looks like.

Romney leading with independents by 14. Weird.

For the record: http://i2.cdn.turner.com/cnn/2012/images/09/10/rel10a.pdf

Romney leads by 14 in a poll where he trails by 6 overall? If they're both carrying roughly similar portions of their base, then this was a fairly Democratic sample. Unfortuantely, I don't see where they identify their sample in the pdf.

Also, note that CNN did something really funky with their methodology. Romney actually IMPROVED among registered voters from the last poll (the same poll that had him and Obama TIED.) He's at 53-45 w/ RV's this week, last week trailed 52-43% w/ RVs.

EDITED to say I was looking at two weeks ago. Last week Obama led by 7 w/ RV's so he had a big improvement with LV's, a smaller improvement with RVs

That's all consistent with a Dem enthusiasm surge wiping out the LV/RV gap.  Gallup and Rasmussen have both picked up renewed Dem enthusiasm.  In 2008, a supercharged Dem year, the LV/RV gap went to all the way 0.  Now it's looking more like a 1-2 point gap this year as opposed to a 3-4 point gap before the conventions.
