WASHINGTON (AP) -- A new Associated Press-GfK poll of likely voters finds that they're evenly divided on whether President Barack Obama's health care law should be scrapped or retooled to make even bigger changes.

First it was the health care overhaul that divided the nation. Now it's the Republican cry for health care repeal.

The AP-GfK poll found that tea party enthusiasm for repeal has failed to catch on, which may be a problem for Republicans vowing to strike down the law if they take over Congress.

Among likely voters, 36 percent said they want to revise the law to do more to change the health care system. A nearly identical share - 37 percent - said they want to repeal it.

Only 15 percent said they would leave the overhaul unchanged.
