Americans are turning against Republican plans to cut taxes as the Senate GOP majority moves closer to passing a tax measure.

Forty-nine percent of Americans who are aware of the plan say they oppose it, up from 41 percent in October, according to the latest Reuters/Ipsos poll. The survey finds that only 29 percent support the Senate GOP plan and 22 percent say they don't know.

If the Senate bill passes, it will need to be reconciled with the House version before either measure can become law. This is by no means assured. But President Donald Trump is pushing legislators to find a tax-cut compromise before the end of the year.

Republican leaders who control both the House and Senate are eager for a bill to pass because they have been unable to find agreement on any major legislation this year and they crave a legislative victory to show they can keep their campaign promises and govern effectively.

Democrats say the GOP favors the rich and big corporations, an argument they have been making for many years.

And the Democratic argument appears to be gaining traction regarding the tax bill. When asked "who stands to benefit most" from the GOP plan, more than half of Americans say either the wealthy or large U.S. corporations. Fourteen percent say "all Americans," 6 percent say the middle class, and 2 percent say lower-income Americans.
