Republicans' timing couldn't be worse when it comes to repealing ObamaCare, at least according to a new NBC News/Wall Street Journal poll released Tuesday. The survey found that right now, just as Republicans have passed the first hurdle toward repeal, Obama's signature health care plan is more popular than ever among Americans.

Forty-five percent of Americans now say the Affordable Care Act is "a good idea," which NBC News noted is "the highest percentage here since the NBC/WSJ poll began asking the question in April 2009." Conversely, 41 percent of Americans say the health care law is "a bad idea."

Even though that's still a large swath of Americans doubting the merits of the ACA, Americans aren't particularly optimistic that Republicans will be able to solve the problem either. Just 26 percent of Americans said they have a "great deal" or "quite a bit of confidence" in congressional Republicans finding a suitable replacement. Fifty percent said they had "very little" or no confidence that the GOP would come up with a viable replacement plan.

The poll was taken from Jan. 12-15 among 1,000 adults. Its overall margin of error is plus or minus 3.1 percentage points.
