For now then, Obamacare doesn't look like a clear electoral winner for either party, meaning the winning message could still be up for grabs or the law simply won't be a difference-maker during the fall election.
On the law itself, 35 percent said it was a good idea and 49 percent said it was a bad idea, effectively unchanged from January.
The new polling comes as both parties are honing their Obamacare messages for the fall races. Democrats plan to offer themselves as the "fix" party, opposed to the GOP's unrelenting obstruction, while Republicans still appear uncertain how to run against the law without opening themselves up to attacks that they'd strip health coverage from the millions who have gotten it.
The poll, conducted from March 5 to 9, surveyed 1,000 U.S. adults. The margin of error is 3.1 percentage points.
