Senate Minority Leader Mitch McConnellMitch McConnellOvernight Energy: Trump energy nominees face Congress | OPEC to extend production cuts Senate confirms Trump's first lower-court nominee Top GOP senators tell Trump to ditch Paris climate deal MORE's (R-Ky.) net favorability rating stands at negative 17 percent, the lowest among all congressional leaders. 

According to a Gallup poll released Thursday, only 23 percent of people have a favorable view of the Senate Republican Leader, compared to 40 percent who have an unfavorable view.

Another 37 percent have no opinion of him. 

The GOP senator, who is facing a tough election this year in Kentucky, has never received a net positive rating in Gallup polling.

House Minority Leader Nancy Pelosi trails shortly behind, with a negative 16 percent favorability rating. While her favorable rating (33 percent) is 10 points higher than McConnell's, her unfavorable rating is also 9 points higher (49) percent. Only 18 percent have no opinion of her.

MORE (D-Nev.) trail shortly behind. Each holds a net favorability rating of negative 14 percent. 

Boehner is seen in a favorable light by 31 percent of people, compared to 45 percent who see him as unfavorable. Another 23 percent have no opinion. 

Reid holds a 27 percent favorable rating, compared to 41 percent who see him as unfavorable. Another 32 percent express no opinion. 

The poll found congressional leaders, while still in the red, have made modest gains since near-record lows during the government shutdown last October. 

Gallup also found that the favorable rating of Boehner and McConnell is much higher among Tea Party Republicans than non-Tea Party Republicans. Boehner's net favorability rating is 23 points higher among Tea Party Republicans, while McConnell's rating is 17 points higher.

"Tea Party draws much of its support from Americans who are similar ideologically to traditional Republicans, whereas non-Tea Party Republicans are more likely to identify as liberal or moderate," Gallup wrote in an analysis. "This could explain the higher levels of support for Republican leadership among Tea Party supporters, despite the historical tensions between the Tea Party and the Republican establishment."

The poll surveyed 1,513 people from April 24-30 and has a 3 percent margin of error.
