Stories here and here about misleading slate mailers, with purported endorsements that don’t exist. This wouldn’t be the first report of such things in Maryland. This time there’s a twist, though: given the recommendations on the mailer in question, one of the pictured candidates is apparently suggesting that citizens vote for his opponent.
In most states, the mailer might give rise to a tort lawsuit, but I’m not sure what an Attorney General’s investigation would yield: slate pamphlets fraudulently claiming an endorsement aren’t generally criminal. That was one motivation for the federal Deceptive Practices and Voter Intimidation Prevention Act.
