Washington (CNN) - Just hours before the House of Representatives is scheduled to begin debate on repealing the nation's new health care law, a new national poll indicates that given the same choice lawmakers will face between repealing the whole measure or keeping it all in place, half of all Americans prefer repeal.
A CNN/Opinion Research Corporation survey, released on Tuesday, also indicates wide partisan and generational divides over the issue.
Tuesday's debate and a scheduled House vote on Wednesday fulfills a campaign promise by congressional Republicans to attempt to repeal health care reform, but also sets up a clash with President Barack Obama and Senate Democrats.

According to the poll, when asked if they would rather see Congress vote to repeal all of the provisions or keep them in place, 50 percent of all Americans favor repeal - even though only one in six dislike everything in the bill. Four in ten oppose such a move.
"Some provisions of the new health care law, such as changes that prevent health insurance companies from denying or dropping coverage for sick people, are extremely popular, and nearly eight in ten Americans say they like at least some aspects of the health care law," says CNN Polling Director Keating Holland. "Polls tend to show that Americans would like to repeal some parts of the new law and keep others. But that option won't be available to lawmakers when the House votes this week."
A Quinnipiac University national poll that was also released Tuesday offered similar results. According to the survey, Americans by a 48 to 43 percent margin want Congress to repeal the health care reform.
As expected, the CNN poll indicates a wide partisan divide, with less than a quarter of Democrats in favor of repeal. That number jumps to 47 percent among independent voters and 84 percent among Republicans questioned in the survey.
According to the poll, a generation gap also exists. People over the age of 50 favor repeal by a 57 to 37 percent margin. But those under the age of 50 are split.
"It's possible this is due to the fact that the first provisions of the new law to take effect have benefited younger Americans," adds Holland. "Or it may be an indication that older Americans are concerned that the new law may affect their Medicare benefits."
The CNN/Opinion Research Corporation poll was conducted Jan. 14-16, with 1,014 adult Americans questioned by telephone. The survey's overall sampling error is plus or minus 3 percentage points.
