A standard public line for presidents is that they don’t make policy based on opinion polls.

But we’re fairly certain no president likes to see his poll numbers drop. Well, President Barack Obama may want to cover his eyes for this one.

OBAMA/The latest Quinnipiac University National Poll found that Obama’s approval rating has dropped to a net low, with 44 percent saying they approve compared with 48 percent who disapprove of how he’s doing his job.

The poll also says independent voters have turned on him  – which other polls have also found. The survey of more than 2,000 voters found a majority of independents disapproved of Obama, 52 to 38 percent, and by 37 to 27 percent said they would vote for a Republican in the 2012 presidential election.

The kicker in the Quinnipiac poll is that more voters said they would pick an unnamed Republican over Obama in 2012, by 39 percent to 36 percent. If Obama faced Republican Sarah Palin, however, Obama comes out ahead.
