Devil's in the Details

Quinnipiac/NYT/CBS released a poll of three swing states:

Including voters leaning toward a candidate, Mr. Obama holds a six-point lead in both Florida and Ohio and an 11-point lead in Pennsylvania. In Florida, 51 percent of likely voters favor Mr. Obama, compared to 45 percent who lean toward Mr. Romney. In Ohio, Mr. Obama holds a 50 percent to 44 percent advantage, and in Pennsylvania, he holds a 53 percent to 42 percent lead.

However, just as I was about to toss my cookies in disbelief, I came to the penultimate para:

While the numbers on their face appear favorable for Mr. Obama, there was also a greater sample size of Democrats in the poll. Thirty-six percent of Florida voters identified themselves generally as Democrats, compared to 27 percent Republicans and 32 percent independents. The split was nearly identical in Ohio, with 35 percent saying they were Democrats, 27 percent Republicans, and 32 percent independents. In Pennsylvania, 38 percent considered themselves Democrats, 32 percent Republicans, and 26 percent independents.

Yep, cheating is the key to understanding the left.
