Opposition from Nebraska Gov. Dave Heineman has killed a bill that would allow machine bets on previously run horse races.
Lawmakers narrowly failed to override Heineman's veto Wednesday, and they defeated an attempt by the bill's sponsor to reconsider their vote.
The first vote was 28-20, two votes short of the minimum lawmakers need to override.
Omaha Sen. Scott Lautenbaugh filed a motion to reconsider the vote, but the request fell one vote short of the 30 it needed.
Bill supporters say the bill would preserve jobs in the flailing horse racing industry.
Heineman and other opponents in the Legislature insist that the bill would create a new form of gambling.
Heineman says the bill contradicts the spirit of live horse racing, which has been approved by Nebraska voters.
