WASHINGTON (CBS DC) — Four years after the law’s passage, the Affordable Care Act remains unpopular with the American public, with a majority (53 percent) of U.S. adults saying they disapprove of President Obama’s signature health care legislation.

A new national survey from the Pew Research Center finds that 53 percent of Americans disapprove of Obamacare as it passes its four-year anniversary on Mar. 23. Four-in-ten (41 percent) of the 3,334 U.S. adults surveyed said they approve of the law, which shows that opinions over the health care law are virtually unchanged from the same Pew survey last September.

According to Pew, A majority of ACA opponents – representing 30 percent of the American public overall – want politicians to do what they can to make the law work as well as possible, compared with 19 percent of the public that wants elected officials to do what they can to make it fail.

And the wide partisan divide over the health care law shows no signs of slimming.

Nearly three-quarters (72 percent) of Democrats approve of the Affordable Care Act, compared to just 37 percent of independents and only 8 percent of Republicans.

And both Republicans and Democrats are looking to use the health care law to their advantage as the 2014 midterm elections draw closer.

On Thursday, both President Obama and Nancy Pelosi touted the benefits of the health care law, while Republicans took the opposite approach.

Pelosi hailed the law’s benefits to the country, noting that nearly 5 million people have signed up for insurance through the ACA’s marketplaces.

“Thanks to the Affordable Care Act, millions of Americans are enjoying newfound health security and the personal and economic freedom that comes with it,” said Pelosi, according to CBS News.

“Any bill that’s passed is not perfect,” said Pelosi. “I wanted single payer. I wanted public option. So, you know, I had some changes I would make myself, but as the implementation takes place, as we see improvements that can be made to any compromise — which the bill was — will do that. But just because people say, ‘I don’t want to repeal it but I do want to fix it,’ doesn’t mean they’re walking away from it.”

Asked whether Obamacare is a “winner or a loser politically,” Pelosi responded, “I believe that it’s a winner.”

Meanwhile, Republican Senate candidate Scott Brown attended an event for New Hampshire Republican Herb Richardson in which he labeled Obamacare a “monstrosity,” although Richardson had previously called the law a “financial lifesaver” for him and his wife.
