More people disapprove than approve of Obama on four domestic issues: the economy, taxes, health care and the federal budget deficit.

The biggest drop has been on his handling of the economy, down 12 points since February; his disapproval is up 19 points. The most erosion has come not from Republicans or independents but among his own Democrats. Support from conservative and moderate Democrats is down by 18 points. Another group in the party's political base — those earning $20,000 to $50,000 a year — had a drop of 15 percentage points, to 47%.

For Obama, the timing of his slide in ratings is particularly unhelpful: He's intensified his push to pass health care bills in the House and Senate before Congress leaves on its August recess. He'll press his case at a news conference at 8 p.m. Wednesday.
His overall approval rating has dropped 9 percentage points since his inauguration in January, and his disapproval rate has jumped 16 points, to 41%.
