President Obama's approval rating has dropped to 47 percent, a new low, according to the Rasmussen Reports daily tracking poll. 

The survey released Thursday showed 52 percent of those polled disapprove of Obama's performance, while 47 percent at least somewhat approve. 

The poll appears to reflect the growing discontent over the health care reform push on Capitol Hill, as well as the continuing challenge Obama faces in trying to turn public opinion. 

The new survey showed 42 percent favor the Democrats' health care plan, while 53 percent oppose it. 

Obama's approval rating has been steadily creeping downward in recent weeks. 

A Quinnipiac University poll last week pegged that number at 50 percent. 

The Gallup tracking poll still shows Obama's approval rating at 53 percent. 

Rasmussen surveys 500 likely voters per night for its tracking poll and reports results based on a three-day average -- for the full sample of 1,500 likely voters, the margin of error is 3 percentage points.
