A slim majority of Americans want Congress to repeal the Obama administration's healthcare reform law, a new poll reported Tuesday.

The poll by Quinnipiac University Polling Institute, released today, found that 48 percent of Americans want the Republican-controlled Congress to repeal the reform legislation, while 43 percent want the law to stay in place.

The poll's results come on the same day that House Republicans open up floor debate for repealing the legislation. The House is scheduled to vote on repeal Wednesday.

According to Quinnipiac, the slight over-all support for repeal is because of independents. Fifty-four percent want the law repealed, 37 percent do not. Among Democrats and Republicans the divide is much wider — 76 percent of Democrats support the healthcare reform law and 83 percent of Republicans oppose it.

"The Republicans pushing repeal of the health care law have more American people on their side. They may not have the votes in the Senate, but they have many on Main Street," Quinnipiac University Polling Institute assistant director Peter A. Brown said. "While President Obama's poll rating has improved in recent weeks, the coalition against his health care plan remains and is quite similar to the one that existed when his numbers were at their nadir."

But the poll also has some positive news for the Obama administration and Democrats. Quinnipiac found that 54 percent of Americans think the economy is improving due to President Obama's policies. Forty-three percent think the economy is not on the upswing.
