Republican and Republican-leaning independents generally had a negative view of the investigation when it started in May 2017, but see it in a much more positive light now that it is over. Fully 60% of the Republicans surveyed this month said they believed the Mueller probe to be somewhat or very fair. That’s a jump of 21 percentage points from January, when only 39% of Republicans held that view. Republicans and Republican leaners who have heard a lot about the Mueller probe or have been following it closely showed the greatest change. Only 29% said in September that the investigation was fair, but that number more than doubled to 62% in July’s survey. Even those who had not heard much about the investigation had increased confidence in its fairness, according to Pew.

Around 70% of Democrats have consistently expressed confidence in the investigation from the start. Unlike Republicans, “there has been little change in Democrats’ confidence in Mueller, regardless of how much they have heard about the investigation,” the Pew report says. However, Democrats are much less confident than Republicans that the Trump administration is making a serious effort to prevent further Russian interference in American elections. Republicans have gained confidence in the administration’s efforts since March 2018, but Democrats’ opinions haven’t changed much.
