The bill that passed was not consistent from a moral basis for banning gambling, as it carved out exceptions for horse racing and state lotteries. In other words--this was a bill that Jack Abramoff would have loved.
Arizona's Representatives voting in favor of the ban: Trent Franks, J.D. Hayworth, Rick Renzi, John Shadegg (all Republicans).
Arizona's Representatives voting against the ban: Jeff Flake (R), Raul Grijalva (D), Jim Kolbe (R), Ed Pastor (D).
(Hat tip to The Agitator. I second his question about why the heck the Washington Post gives a vote breakdown by Representative's astrological sign.)
