Today a slew of heavily D/I weighted polls designed to show that Barack Obama is getting more popular. Really. First CNN with it’s notoriously overweighted system.

“Washington (CNN) – President Barack Obama’s approval rating, a crucial indicator of his reelection chances, is on the rise, according to a new national survey.

A CNN/ORC International Poll out Tuesday also indicates that the partisan battle over extending the payroll tax cut may be partially responsible for the jump in the president’s numbers.

According to the survey, 49% of Americans approve of the job Obama’s doing in the White House, up five points from last month, with 48% saying they disapprove, down six points from mid-November. The 49% approval rating is the president’s highest since May, when his number hit 54% thanks to a bounce following the killing of Osama bin Laden. Since then, in CNN polling, Obama’s approval rating has hovered in the mid-40s.

“President Barack Obama’s approval rating appears to be fueled by dramatic gains among middle-income Americans,” says CNN Polling Director Keating Holland. “The data suggest that the debate over the payroll tax is helping Obama’s efforts to portray himself as the defender of the middle class.”

Some demographics of this laughable poll? Ed Morrisey of Hot Air fills it in.

“As in the earlier post on the Republican primary results, one has to keep the sample skew in mind. The D/R/I of 32/25/37 in the current sample may have a D+7 and a ridiculous I+12 skew against Republicans, but in the poll series dealing with Obama, it’s not as bad as the skew in some previous surveys. However, it is worse than the last full poll in this series, which had a D/R/I of 29/26/38.

So what happens when you add four points to the gap between Democrats and Republicans in a poll? You go from a job approval rating of 44/53 at the beginning of November to 49/47 today. Obviously, not all of this improvement can be attributed to the change in the sample skew, but some of it surely can.”

In other words it’s crap poll juice.
