I’ve got good news and bad news for Hot Air readers today. First, the good news: After a few years of embarrassing sample skew problems in the CBS/NYT polls, the two media outlets have partnered with Quinnipiac, at least for this week’s look at three swing states — Florida, Ohio, and Pennsylvania.  The bad news?  I’m not sure the new partnership improved things.

First, let’s look at CBS’ lead on the new poll numbers, which they tout as good news for Barack Obama and bad news for Mitt Romney:

President Obama leads Mitt Romney among likely voters in Ohio and Florida – and has a double-digit lead in Pennsylvania – according to a Quinnipiac University/CBS News/New York Times poll released this morning.

The poll, conducted from July 24-30, shows Mr. Obama leading his presumptive Republican challenger 53 percent to 42 percent in Pennsylvania. The 11-point lead results largely from independents, who favor the president by 22 points, and women, who favor the president by 24 points.

Mr. Obama holds a six-point lead in Ohio, 50 percent to 44 percent, a state where he holds a campaign event later today. His lead here is also due in large part to women, who back him by a 21-point margin. Romney leads by ten points among Ohio men, and seven points among Ohio whites.

In Florida, Mr. Obama also holds a six point lead, 51 percent to 45 percent. He holds a small lead among both men and women and a 19-point lead among Hispanics, while Romney leads by double-digits among whites and voters age 65 and above.

Now let’s take a look at the partisan breakdown (D/R/I) in the sample data for each state, and compare them to 2008 and 2010 exit polling:

• Florida: CBS/NYT 36/27/32, 2008 37/34/29, 2010 36/36/29
• Ohio: CBS/NYT 35/27/32, 2008 39/31/30, 2010 36/37/28
• Pennsylvania: CBS/NYT 38/32/26, 2008 44/37/18, 2010 40/37/23

The CBS/NYT model has Democrats a +9 in Florida when in 2008 they were only a +3 and an even split in the 2010 midterms.  Ohio’s sample has exactly the split in 2008 (D+8), which is nine points better than Democrats did in the midterms.  Pennsylvania’s numbers (D+6) come closest to a rational predictive model, somewhere between 2008’s D+7 and 2010’s D+3, but still looking mighty optimistic for Democratic turnout.

In other words, these polls are entirely predictive if one believes that Democrats will outperform their turnout models from the 2008 election in Florida and Ohio. That would require a huge boost in Democratic enthusiasm and a sharp dropoff in Republican enthusiasm — which is exactly the opposite that Gallup found last week.

CBS/NYT polling: New partner … same issues.
