Vance, 3 other House Dems switch to GOP | oanow.com: "State Rep. Lesley Vance of Phenix City and three other House Democrats switched parties Monday, saying they identified more with Republicans.
“We have been kidded over the years that y’all are more conservative than some of the Republicans,” Vance said.
The moves give the GOP 66 votes in the House, or a super-majority allowing them to pass legislation without support from Democrats.
House Democrats Mike Millican of Hamilton, Steve Hurst of Munford and Alan Boothe of Troy joined Vance to announce the switch at a news conference Monday in Montgomery. The four represent Republican-leaning, mostly white areas."
