A majority of American voters, 56 per cent, disapprove of the Republican health care plan to replace the Affordable Care Act or Obamacare, according to a poll.

Only 17 per cent of voters approve of the plan and 26 per cent remain undecided, the Quinnipiac University poll revealed on Thursday.

The question -- "There is a Republican health care plan to replace Obamacare, known as the American Health Care Act. Do you approve or disapprove of this Republican health care plan?" -- did not go into specifics of the plan.

"Replacing Obamacare will come with a price for elected representatives who vote to scrap it, say many Americans, who clearly feel their health is in peril under the Republican alternative," CNN quoted Tim Malloy, assistant director of the poll, as saying.

Most voters, 61 per cent, also disapprove of the way President Donald Trump is handling health care.

The President and Republican leaders are scrambling for a deal on landmark legislation to repeal and replace Obamacare. Republicans cannot lose more than 21 members of their party and still pass the bill, since no Democrats are expected to support it.

One out of every seven Americans -- 14 per cent -- believes they will lose their health insurance under the Republicans' replacement plan.

The plan itself does not enjoy majority support among Republicans, with only 41 per cent backing the bill, reports CNN.

Most men, 56 per cent, disapprove of the plan as do most women, also 56 per cent.

While more than half of white voters disapprove of the plan, even more non-white voters -- 64 per cent -- disapprove.

Overall, 58 per cent of independent voters disapprove of the replacement plan.

Quinnipiac University surveyed 1,056 voters nationwide from March 16 to 21.
