Two months after the U.S. Congress adopted a new tax plan, Montanans remain uncertain about its future impacts, both on a personal and state level, according to a new University of Montana poll.

Released on Tuesday, the poll found that 41 percent of Montanans disapprove of the tax plan while 34 percent approve and 21 percent remain unsure.

But in no surprise, the level of support for the tax plan varied by political party and income.

Republicans showed strong support at 65 percent while Democrats disapproved at 79 percent. Independent voters were more divided, with 39 percent disapproving and 34 percent in favor.

Forty-eight percent of individuals who make less than $37,000 annually had the strongest level of disapproval, the poll found.

The poll was conducted via telephone between Feb. 1 and Feb. 19 with 603 randomly selected Montana registered voters. The poll has a margin of error of +/-4 percentage points.
