People in these states should vote out any of their legislators that do this and nullify their votes.
Via Daily Wire:
If Nevada’s Democratic governor signs a bill passed by the state senate Tuesday into law, his state will have moved the National Popular Vote movement six votes closer to effectively nullifying the Electoral College as established in the U.S. Constitution.
By a vote of 12-8, the Nevada Senate passed AB 186 on Tuesday, which if signed by Gov. Steve Sisolak, will add Nevada’s six electoral votes to the 189 votes already pledged by 14 other states in the National Popular Vote Interstate Compact, which would “guarantee the Presidency to the candidate who receives the most popular votes across all 50 states and the District of Columbia.” If triggered, the pact would override the majority decision of voters in particular states.
