Courtesy of the thugs at AFL-CIO, the pamphlet warns that your voting history is a matter of public record. In other words, "we know who you are, and we'll know how you voted". Inside, they provide helpful information regarding the "correct" way to vote.
It's an updated version of a tool that's served them well in the past: "Nice little place ya got here. Be a real shame if something was to, you know, happen."
It may be an effective intimidator for some folks, but of course it's predicated upon a lie: the fact that you voted is public record; how you voted is not. Even rabid Kate Brown, supported by union thugs, knows that any effort on her part to alter that would encounter an insurmountable wall of litigation. She probably hopes that it's sufficient to violate the law by not destroying unused ballots after 8 p.m. on election day.
It's interesting that they'd decide now to stoop to such tactics; clearly, this election has them very concerned, even in regard to the reliably Democrat Portland metropolitan area. Despite all of the mud-slinging against her Republican opponent during the past week or so, Kate Brown may very well lose her job; when virtually no media support her and several have endorsed her opponent, her many union endorsements suddenly become less compelling. That race alone may explain the thugs' decision to resort to thinly-veiled intimidation tactics.
Their problem is that it's already starting to backfire among recipients of the pamphlet.
