A committee in the Iowa Senate has voted to eliminate a requirement that local voters approve gambling every eight years to keep a casino open. Under the bill, once a county had approved gambling twice, the automatic referendums on gambling would end and counties would have to wait eight to 15 years for a vote. Senator Dennis Black, a Democrat from Grinnell, is pushing the bill, as he says the vote can hamper the development of a casino.   http://www.radioiowa.com/gestalt/go.cfm?objectid=0E5680A2-A057-809B-5F4BF5E7ACA155C8
