Legislation in Lansing is designed to give Michigan's struggling horse racing industry a boost.
MLive.com reports proposed changes to the state's horse racing law would permit raceways to install machines allowing customers to bet based on past races. Bettors get some information provided in programs for live races, but not details to let them know the outcome in advance.
The measure was approved 91-16 last week in the House and is pending in the Senate.
Supporters say it would give horse tracks a modern gambling attraction.
Some Michigan casino interests say, however, that because of a 2004 constitutional amendment, state and local voters also must approve the change.
Tracks with live racing include Mount Pleasant Meadows, Sports Creek Raceway in Swartz Creek, Hazel Park Harness Raceway and Northville Downs.
