Veto override a possibility for second Montana sports betting bill Jill R. Dorson, SportsHandle · May 14, 2019 at 8:02 pm After 87 legislative days that ended April 20, Montana Senator Mark Blasdel is back to his everyday life as a caterer. But he’ll have to interrupt serving up canapes to do just a little bit more lobbying. The Montana State Legislature overwhelmingly passed Blasdel’s sports betting bills in the waning days of the session, only to watch Governor Steve Bullock veto it in favor of a bill that puts the state lottery in charge. But all isn’t lost for Blasdel’s measure. Under Montana law, any bill that passes the state legislature by two-thirds as SB 330 did, is automatically up for a veto override. And last Friday, the veto-override process started. If two-thirds of the members of both the state senate and house approve the bill, it becomes law.
