PORTLAND, Maine (AP) — A sports betting proposal in the Maine Legislature is dead. The Maine House on Tuesday did not reach a two-thirds majority needed to override a veto by Democratic Gov. Janet Mills. The Senate voted last week to override the veto by a single vote. The governor said Tuesday that the House made the right decision and she urged lawmakers to “slow down.” The bill would have allowed casino operators, off-track betting facilities, Native American tribes and harness racing tracks to host sports betting with wagering taxed at 10%. Online and mobile betting would have been permitted at a higher tax rate of 16%.
