(Salem, OR) -- State lawmakers are signing off on a bill moving the referendum on the transportation funding law from November to the May Primary election. The Oregon House voted 31-20 yesterday to pass the bill, which now moves to Governor Tina Kotek's desk for a signature. Democrats say they need to know the outcome of the vote so they can start preparing a new transportation plan. Republicans say it's political. Governor Tina Kotek is running for re-election, and the transportation referendum would be on the same ballot.
