MILWAUKEE — Following the announcement that the federal investigation by special counsel Robert Mueller has concluded, a new Marquette University Law School Poll finds a range of reactions to what is known of those conclusions, as well as modest changes in evaluations of President Donald Trump.

Forty-six percent of registered voters in Wisconsin approve of the job Trump is doing as president, while 52 percent disapprove. In January, 44 percent approved and 52 percent disapproved.

Support for reelecting the president is also little changed since January — 28 percent say that they would definitely vote to reelect Trump, and 14 percent would probably vote to reelect him. Another 8 percent say that they would probably vote for someone else, and 46 percent would definitely vote for someone else. In January, 27 percent said that they would definitely vote to reelect Trump, 12 percent said that they would probably vote for him, 8 percent that they would probably vote for someone else and 49 percent that would definitely vote for someone else.

Based on what respondents have heard about Mueller’s report so far, 42 percent say they have a great deal of confidence that the investigation was fair and impartial, 25 percent say they have some confidence, 10 percent have only a little confidence and 14 percent say they have no confidence at all in the fairness of the investigation. When the question was last asked in early October 2018, 31 percent said they had a great deal of confidence in the fairness of the investigation, 19 percent had some confidence, 13 percent had only a little confidence and 26 percent said they had no confidence at all.

Confidence in the Mueller investigation rose among Republicans and independents, while it declined among Democrats. Among Republicans, the percentage expressing a great deal of confidence rose from 12 percent in October to 43 percent in April, while those having no confidence at all declined from 38 percent in October to 19 percent in April. Among independents, the proportion of those who said they had a great deal of confidence increased from 29 percent in October to 41 percent in April. Independents with no confidence in the investigation declined from 25 percent to 14 percent. Among Democrats, those expressing a great deal of confidence declined from 58 percent in October to 45 percent in April, but those Democrats with no confidence also declined from 13 percent to 8 percent, as more Democrats picked the “some confidence” or “only a little confidence” options.

While the full Mueller report had not been released at the time of the April poll, respondents express a range of conclusions based on what they have heard about the report.

A majority, 60 percent, think that Russia interfered with the 2016 presidential election, while 32 percent think Russia did not interfere.

Thirty-five percent think the Trump campaign colluded with Russia to influence the 2016 election, while a majority, 53 percent, think the campaign did not collude.

Opinion is evenly divided on whether Trump tried to obstruct the investigation, with 45 percent saying he did and 45 percent saying he did not.

While 39 percent say the investigation clears Trump of any wrongdoing, 54 percent say they believe questions still exist concerning the president’s behavior.

Support for beginning hearings on impeachment stands at 29 percent, down from 33 percent in January. Those saying that there is not enough cause for impeachment hearings rose to 65 percent in April from 59 percent in January.

Those who say “honest” describes President Trump rose to 35 percent in this April poll from 31 percent in January. Fifty-nine percent in the new poll say “honest” does not describe him, compared to 62 percent in January.

The poll was conducted April 3-7, 2019. The sample included 800 registered voters in Wisconsin interviewed by cell phone or landline, with a margin of error of +/- 4 percentage points.
