Senators voted 23-12 Thursday to approve the bill, which was scaled back from its original version that would have allowed 400 slots. The House also gave its final OK Thursday, by a 98-34 roll call vote.
But its future is in question, given Baldacci’s opposition and history of vetoing gambling bills. A two-thirds vote by both houses is needed to override a veto.
Supporters say the Penobscots need the slot revenue to run community services. Opponents say Maine voters just last fall rejected a gambling proposal for Washington County.
