Some evidence that the situation is more complicated is the recent primary where labor-backed Rep. John Dingell beat EMILY's List-backed Rep. Lynn Rivers. http://www.michigandaily.com/vnews/display.v/ART/2002/08/07/3d51488cd17f8 "While Rivers and Dingell share many core Democratic principles, their views differ on a couple issues, most notably gun control and a woman's right to choose. The National Rifle Association endorsed Dingell for the primary, while Rivers supports stricter background checks and required safety locks for handguns. Meanwhile, the National Abortion and Reproductive Rights Action League recently gave Rivers a score of 100 on her abortion record, while Dingell received a 65."
