Following Special Counsel Robert Mueller’s invasion of the office and home of President Trump’s personal lawyer, voters increasingly believe Mueller’s probe is politically biased. But they also tend to think he is unlikely to nail the president for anything criminal.

The latest Rasmussen Reports national telephone and online survey finds that 46% of Likely U.S. Voters still believe Mueller’s investigation is an honest attempt to determine criminal wrongdoing, but that’s down from 52% last October. Forty percent (40%) now consider Mueller’s probe a partisan witch hunt, an eight-point increase from 32% in the earlier survey. Fourteen percent (14%) are undecided.

The survey of 1,000 Likely Voters was conducted on April 10-11, 2018 by Rasmussen Reports. The margin of sampling error is +/- 3 percentage points with a 95% level of confidence. Field work for all Rasmussen Reports surveys is conducted by Pulse Opinion Research, LLC. See methodology.
