Here's how pundit Greg Sargent summed up the results from the Pew Poll:
The approval rating of GOP leaders among Republicans has plummeted 12 points in a month, down from 55% in February to a minority of 43% now. That’s striking.
Not only that, but approval of GOP leaders overall has dropped to 28% overall — the lowest rating for GOP leaders in 12 years of Pew polling.
In fact, approval of Republican congressional leaders has fallen from 34% in February to 28% currently, the lowest rating for GOP leaders in nearly 14 years of Pew Research surveys.
