They needed 28 votes, and 28 votes they got.
Via multiple reports, the Nevada Assembly passed a stadium bill by a vote of 28-13.
The bill as passed by the Assembly now goes back to the Senate for the purposes of ironing out any differences between the two versions of the bill.
The proposal calls for $750 million in taxpayer money to be used to construct a stadium in Las Vegas for the Raiders. The funds would come from the application of a hotel tax.
None of this happens unless the Raiders get the approval to move to Las Vegas, which may or may not happen. Which may or may not deter the Raiders from trying to move without approval.
