President Obama's approval rating has hit another new low, as views of his health-care law have again taken a turn for the worse, according to a new Washington Post-ABC News poll.

The poll shows Obama's approval rating is down to 41 percent, a point below its previous low of 42 percent, in November.

The president's disapproval rating is at 52 percent, three points lower than the previous high. Six percent have no opinion on Obama.

The ebb in Obama's approval comes as a momentary bump in support for his signature health-care law appears to have gone by the wayside. Following some rare good news about the law -- including meeting its sign-ups goal despite a rough launch-- 44 percent of voters approved of his handling of it. That number is now down to 37 percent, with 57 percent disapproving.

Views of Obamacare overall have also dropped after a slight boost. While 49 percent approved of the law last month, 44 percent approve of it this month -- the lowest that number has been since November. Forty-eight percent of Americans disapprove of the law.

Americans also have an increasingly dim view of Obama's handling of the situation in Russia and Ukraine, in which 34 percent approve of him and 46 percent disapprove. Last month, views of Obama's handling of the conflict were evenly split (42 percent positive, 43 percent negative).

The poll was conducted among a random national sample of 1,000 adults. The margin of error is plus or minus 3.5 percent, meaning some of the changes described above aren't statistically significant.
