Mostly as a result of weak support from Democrats and independents regarding the proposed tax changes, only 29 percent of USA adults as a whole approve of the plan, while 56 percent disapprove and 16 percent have no opinion.
Only 5 percent of respondents said they expect low income Americans to benefit the most from Republicans' efforts to overhaul the US tax code.
The opposition of the public, according to the polls, is that the bill gives massive tax cuts to corporations and the wealthiest Americans, while offering only token and temporary breaks to the middle class and increases to the poorest citizens.
President Donald Trump's approval rating dropped three points from a late November survey to 35 percent.
The findings came as congressional lawmakers were set to begin reconciling the differences included in the respective GOP tax overhaul bills that have passed the U.S. House and Senate in recent weeks.

A Gallup poll found that 29% of Americans approved of the bill, while 56% disapproved.
The tax bill now heads to conference committee where representatives from the House and Senate will work to craft compromise legislation that could get through both chambers by month's end.
