They're almost all from competitive districts who moved to the right starting in 2006. That's how the rats took over Congress combined with the dismal GOP performance. That's how they got such a big majority. IIRC, there are 84 Congressional Districts with a rat in the House whose district voted for Bush in 2004 or McCain in 2008. They have a hardcore left leadership, but their majority has a lot of moderates.
Some people choose the party before the person.
But thios is the FIRST Time in My Memory I heard of the Party taking precedence over AMERICA!
What a tragedy!
