The previous high for disapproval of the law was 54 percent in Pew polling. That was at the height of the implementation problems in December.
Forty-three percent of Americans disapprove of the law "strongly" -- also a record high. Forty-one percent of Americans currently approve of the law. That's higher than the record low, 37 percent.
The poll also shows Republicans lead when it come to which party people favor in the 2014 midterm election. While 47 percent favor Republicans, 43 percent favor Democrats.
Pollsters generally agree that, in a neutral environment, Democrats would have a small lead on this measure, the so-called generic ballot. So the GOP's small lead is likely more significant than it seems.
