"ALEC is not a lobby; it is not a front group. It is much more powerful than that. Through the secretive meetings of the American Legislative Exchange Council, corporate lobbyists and state legislators vote as equals on ‘model bills’ to change our rights that often benefit the corporations’ bottom line at public expense. ALEC is a pay-to-play operation where corporations buy a seat and a vote on ‘task forces’ to advance their legislative wish lists and can get a tax break for donations, effectively passing these lobbying costs on to taxpayers.
Along with legislators, corporations have membership in ALEC. Corporations sit on ALEC task forces and vote with legislators to approve “model” bills. They have their own corporate governing board which meets jointly with the legislative board. (ALEC says that corporations do not vote on the board.) Corporations fund almost all of ALEC's operations.
Participating legislators, overwhelmingly conservative Republicans, then bring those proposals home and introduce them in statehouses across the land as their own brilliant ideas and important public policy innovations—without disclosing that corporations crafted and voted on the bills."
