President Donald Trump has signed an executive order that would create a nationwide list of verified eligible voters in each state and bar the U.S. Postal Service from sending mail-in and absentee ballots to voters not on these lists. Oregon Democrats have condemned the order and vowed to fight it in court, with the state's attorney general and secretary of state both pledging immediate legal action. The order is expected to face legal challenges from other states as well. If it stands, it could significantly impact Oregon's pioneering vote-by-mail system. Oregon became the first state in the nation to vote exclusively by mail following a 1998 ballot measure. Critics have accused Trump of attempting to disenfranchise voters in an effort to rig the upcoming November election.
