Not exactly. They “Faked” to the right with Blue Dog canidates in a calculated move to get Nancy Pelosi control of the House. The party never moved an inch to the right in ideology....I’m sure these “Conservative” Democrats were told who REALLY runs things in DC when they arrived the first day. Kind of like how the TEA PARTY Congressman are probably told by Establishment GOP’ers like Boehner the first day how things work.
Most of the party leadership never moved an inch to the right in ideology. Don't forget Harry Reid needed the NRA's emdorsemeent in 2010. They got candidates who were pro Second Amendment or pro life as needed starting in 2006. Bob Casey is a pro life example. In early 2009, 64 rats in the House sent a letter to Holder about renewing the so called assault weapons ban. They told him to pound sand. So we got Fast & Furious. Since they took Congress in 2006 what serious gun grabbing has been done?
