The only reason Pelosi rose to power and remains in power is because she is female and a great fundraiser, she not only is a simple minded hack but she can be blamed for the continuing collapse of the House
As is often the case, the hatred of Pelosi seems to boil down to sexism. Pelosi is not only a great campaigner, but as a legislator, she's one of the best the House has seen in decades. She worked non-f**king-stop to get politically difficult, important legislation passed through the House while Speaker that repeatedly went off to die in the useless Senate. She's 100000x the legislative organizer that Boehner is.
Hate her political opinions all you want, but there's a reason she's still the Democratic leader. She can get s**t done.
