Support for candidates who voted for the health-care law has improved dramatically in recent months, a Washington Post/ABC News poll released Tuesday shows.

The survey found respondents almost exactly split on the question of whether they would be more or less likely to vote for a congressional candidate who supports the Affordable Care Act, with 34% saying they would be more likely to vote for the candidate and 36% saying they would be less likely to do so. Some 27% said it would not make a difference.
