Not true. Oregon and Washington State vote only by mail including federal elections. The Constitution gives the states the right to decide how they vote, which is why some states have early voting, various forms of absentee voting, different voting hours, various primary methods, etc. etc. etc. Trump has no say in how a state votes, but he is using his bully pulpit to make it a campaign issue and to make people aware of the fraud that can occur.
Well, thank you for that correction, Dave.
Figures that its Oregon and Washington :- /
