I actually got one of these mailers the same day I got my absentee ballot. And sure, the mailer is deceptive, especially since the guy they said to vote for isn't running.
Even so, since when is advertising to voters they have different choices "voter suppression"? And more importantly, would The News Tribune be covering this story if this tactic were being used against a Republican candidate?
