Pelosi has a 55% favorable rating among Democrats. This percentage matches the lowest favorability recorded for her in 2009 among her own party. Over the past 10 years, her rating among Democrats reached a high of 66% several times.
On the whole, Pelosi has had persistently net negative image ratings since 2007 when she became speaker. Before that, more Americans had no impression of her than had a favorable or unfavorable opinion of her.
Pelosi ended her term as speaker with an overall 33% favorability rating in 2011, which was somewhat higher than her successor, John Boehner's 23% rating recorded two months before he announced his retirement in 2015. By comparison, Ryan's 40% favorability rating among all Americans makes him the most popular of the last three speakers so far, although his term doesn't end until January 2019. Using history as a guide, Ryan's favorable rating would be expected to worsen as time goes on. All recent speakers left the speakership with net negative favorability ratings, much worse off than when they started.
