Americans oppose Donald Trump's emerging tax plan by a broad 17-point margin, with 60 percent saying its favors the wealthy, including six to 10 of the wealthy themselves.

ABC News reports, as details have emerged, support and opposition have grown in tandem. Fifty percent in the ABC News/Washington Post poll oppose the plan, up six percent points from September: 33 percent support it, up five points. A reported 17 percent are undecided.

A key criticism is the sense that the plan would mostly benefit the rich: 60 percent say so, versus 17 percent who think it will treat all people equally and 13 percent who this think the middle class mainly will benefit.
