The corporate front group the American Legislative Exchange Council (ALEC) has come under increasing fire for secretly passing off corporate-written legislation to state legislatures. Yesterday, the medical device company Medtronic announced that it chose not to renew its membership in ALEC in 2010. Medtronic joins companies including Scantron, which announced earlier this week it was leaving ALEC, as well as Coca-Cola, Kaplan,PepsiCo, Kraft Foods, Wendy’s, Mars, the Bill and Melinda Gates Foundation, and BlueCrossBlueShield.
