President Trump has seen an uptick in his job approval rating since reaching a record low last month, and majority of respondents think the White House has at least partially succeeded in getting Congress to advance its legislative agenda, according to a new poll by Monmouth University.

Forty-two percent of Americans gave Trump a positive approval rating in the new survey, which was released a day after he received high marks for his first State of the Union address Tuesday night. The president carried an approval rating of 32 percent last month, and has since seen a 6 point decrease in the percentage of voters who disapprove of his job performance.

Much of the boost for Trump appears to stem from a positive shift in the public's perception of the tax cut bill, which passed the House and Senate in December and is expected to save middle-income Americans thousands of dollars in taxes beginning next year. Approval of the historic tax reform plan has jumped 18 points – to 44 percent – since last month, when a mere 26 percent of Americans supported the legislation.

Trump's ability to fulfill many of the promises he made during the 2016 election has also impressed a majority of Americans, 55 percent of which said he has been "somewhat successful at getting Congress to pass his legislative agenda."

"The president devoted a significant amount of the State of the Union address touting a growing economy and his new tax plan," Patrick Murray, director of the Monmouth University Polling Institute, said in a statement accompanying the survey results. "While there is still some way to go to really win over the public, it looks like the needle has moved in the Republicans' direction since passage of the tax bill."

Despite the improvement in Trump's overall approval rating, the percentage of voters who fervently support him has slowly declined. Only 50 percent of Americans currently believe the president cannot do anything to change their positive feelings toward him, down from 61 percent last August.

The Monmouth University poll of 806 U.S. adults was conducted between Jan. 28-30. Results contain a margin of error plus or minus 3.5 percentage points.
