EMILY's Lies

Is there a nominally progressive advocacy group more scurrilous than EMILY's list? It seems like I'm constantly seeing them engaging in bogus-to-outrageous attacks on progressive Democrats, in ways that do deep damage to the progressive movement while doing very little (if anything) to push Congress in a pro-choice direction. They were deeply involved in Nikki Tinker's racially and religious-tinged campaign to unseat sterling progressive Rep. Steve Cohen in the 2008 Democratic primary. And right now DKos Elections is on their case adopting GOP-style rhetoric attacking a Democrat for successfully raising taxes on millionaires.
