WASHINGTON (CNN) - Less than one-third of Americans approve of the Republican tax plan, Quinnipiac figures show.
The same poll put President Donald Trump's approval rating at 35 percent, and Gallup's daily tracking poll reported the same percentage.
In the Quinnipiac poll, conducted from Nov. 29 to Dec. 4 -- before the US Senate passed its version of the tax bill in the early hours of Saturday -- almost two-thirds (64 percent) of people surveyed said the bill would benefit the wealthy most, while just 24 percent said they believe the middle class would benefit the most.
Twenty-nine percent of Americans approve of the Republican plan, according to the poll.
Additionally, 41 percent believed the plan would raise their taxes. Before the House of Representatives passed its version of the tax plan, just 35 percent thought they would see a tax hike.
Trump's approval rating remains below 40 percent, a mark he hasn't hit in the Quinnipiac poll since June.
According to a November 9 CNN poll, Trump's approval rating was 36 percent, while in October it was 37 percent.
For this poll, Quinnipiac University surveyed 1,508 voters nationwide, with a margin of error of +/- 3.1 percentage points.
