Barack Obama's getting bad marks from the voters for his handling of the oil spill in the Gulf, but it's not having any impact on his overall approval numbers.
47% of voters express disapproval of how he's dealt with the spill to only 38% who think he's doing a good job. But his overall approval of 48% to 47% of voters disapproving of him is basically identical to what it was a month ago.
85% of the voters who don't like how Obama has handled the spill also don't like his overall job performance so this isn't really something where people who liked him before are turning against him- it's just giving people who already didn't like him one more reason not to.
Obama's approval numbers continue to be remarkably consistent in our national polling. Every month since November his approval has come in somewhere between 46 and 50% and his disapproval has come in somewhere from 46 to 49%. There's no doubt the American public is pretty much evenly divided on its President and there's been little change in those feelings over the last six months.
