SALEM — Oregon is on its way to joining a movement to ignore the Electoral College in favor of the popular vote in presidential elections.

Senate Bill 870 passed the House 37-22 on Wednesday after passing the Senate nearly two months ago. The bill joins Oregon in a group of 15 states supporting the effort to have the popular vote reflected in ballots cast in the Electoral College. The bill now goes to Gov. Kate Brown, who has supported the popular vote since her time as secretary of state. She will sign it, a spokeswoman said.

With Oregon, the states would control 196 electoral votes. The compact would only go into effect if enough states joined to reach the 270 electoral college votes needed to decide an election.

Another eight states have passed national popular vote bills through at least one legislative chamber. If all eight states passed it, that would add another 75 votes, according to the movement’s website. That would be one more electoral vote than needed.
