Republican legislators are showing concern that their tax reform legislation is not being received well by the public, so they need to do better at presenting the plan to middle-class and low-income voters, according to The Hill.

A CBS News poll released Thursday showed 53 percent disapproved of the tax reform plan. Large majorities of voters believe the plan will help corporations and the wealthy, not the middle class, CBS News reported.

On Friday, Sen. Marco Rubio, R-Fla., said that Republicans must not become tied to the "country club-big business image," referencing a famous speech that Ronald Reagan gave in 1977, the report said.

Some worry about those who would see little benefit from the reforms. Rubio and Sen. Mike Lee, R-Utah, attempted to amend the Senate legislation to give more help to lower-income voters by making the child tax credit refundable.

However, while 20 Republicans voted for the amendment, it failed, The Hill reported.

"It makes a lot of sense in a tax reform bill to provide some relief to those on the lower end of the income scale as well as the upper end," pollster Whit Ayres told The Hill.

"I think we have got to do a better job of communicating to America what's in this," said Sen. David Perdue, R-Ga., who opposes having the corporate tax rate any higher than 20 percent.

"We've got to figure out how to communicate better," said Sen. Rob Portman, R-Ohio.

"It depends on how you ask the corporate (rate) question. If you ask, ‘Do you think we should make American companies competitive by getting the rate below the (global) average?' The answer is yes," Portman said, according to The Hill.

Polls by Quinnipiac and Gallup also showed high disapproval ratings for the tax plan, The Hill reported.

A USA Today poll released Sunday also showed poor results for the tax reform plans. A majority of Americans are skeptical that the tax bill will reduce their taxes.
