A new poll suggests that Americans back Republican tax cut plans but not the GOP's campaign to repeal President Barack Obama's health care overhaul.

The findings of the Associated Press-GfK Poll suggest that the Republicans' big win in last week's elections was not a mandate for the party's legislative wish list.

Fifty-three percent in the poll said income tax cuts that soon will expire should be renewed for all, including the highest earners. But 44 percent would continue the cuts only for those earning under $250,000 a year - which Obama favors - or let them lapse for everyone.

Just 39 percent back the GOP effort to repeal the new health care law or scale it back. Fifty-eight percent would rather make even more changes in the health care system or leave the measure alone.
