MSNBC prime-time host Rachel Maddow has seen her monthly ratings drop more than 800,000 viewers since the beginning of 2019.

Maddow had her best month of 2019 in January, where she averaged an audience of 3,288,000 viewers, according to Nielsen Media Research. She saw a decrease in February with her average audience dropping to 3,067,000.

The host has not exceeded an average of 3,000,000 viewers a month since then.

She continued the downward spiral in March and April as her average audience size was 2,886,000 in March and then 2,630,000 in April. Her decline in ratings over this two month period corresponds to the end of the Russia investigation.

Maddow was one of the leading voices in the speculation surrounding the special counsel's report into whether or not the president or his campaign conspired with Russia to win the presidential election. In the week after Attorney General William Barr's letter to Congress where it was revealed that Mueller found no evidence of a conspiracy, Maddow lost half-a-million viewers, according to the Daily Beast.

Her ratings continued to drop through the spring and into the summer. In June and July, her nightly average audience dipped below the 2.5 million marker only reaching 2,450,000 in June, but hit a little bump to 2,487,000 in July. The slight bump in July might be attributed to the recent revival of the report as Mueller himself testified before Congress.
