Story highlights The Pew survey shows support for Obamacare at an all-time high

Support for the law has risen amid Republicans' push to repeal and replace it

(CNN) Support for Obamacare is at an all-time high, according to two surveys released this week as Republican leaders continue to press the case for repeal amid fierce resistance at many town halls.

The latest Health Tracking Poll from the Kaiser Family Foundation found that 48% of Americans view the law favorably, compared to 42% who have an unfavorable view. This is the highest level of favorability measured in more than 60 Kaiser Health Tracking Polls conducted since 2010.

The boost comes largely from independents, half of whom view Obamacare favorably compared to 39% who don't. Nearly three-quarters of Democrats continue to view it favorably, while about the same share of Republicans have an unfavorable view.

Also, a survey from the Pew Research Center found 54% of Americans approve of the Affordable Care Act -- the highest level ever recorded by Pew -- while 43% disapprove. That's up from an even split (48%-47%) in a Pew survey from December, suggesting support for the law may be galvanized by the ongoing public fight over its future.

Still, opinions on Obamacare remain divided. Predictably, Republicans are most likely to say they disapprove (89%) while Democrats are most likely to express approval (85%). But slightly more independents say they approve (53%) than disapprove (45%) -- up about 10 points from December.
