Months of sustained conservative attacks led by President Donald Trump and his allies has harmed Mueller most among Republicans, with a record 53 percent now saying they view the lead Russia investigator in an unfavorable light. That’s a 26-point spike since July, when the poll first started asking voters whether they viewed Mueller favorably or unfavorably.

Mueller’s unfavorable numbers have hit highs among both Democrats and independents, at 24 percent and 33 percent, respectively. Thirty-six percent of all registered voters are also seeing Mueller unfavorably, which represents the highest level since the polling first raised the topic 11 months ago. Back then, 23 percent of all voters said they viewed Mueller negatively.

The spike in the special counsel’s unfavorable ratings come as he begins his second year on the job.
