Nationwide, campaign signs have been defaced or simply have vanished, leaving the candidates' supporters seething.
Local party leaders in western Michigan's Ottawa County and in central Ohio's Licking County say hundreds of Trump and Clinton signs have been vandalized or stolen.
A Massachusetts man rigged a fake booby trap around a Trump yard sign after two other signs went missing; in battleground Pennsylvania, a woman duct-taped alarms and trip wires to her two Clinton signs. Also in Pennsylvania, a man says he's had 13 Trump signs stolen, one by a man wearing goggles and a hazmat suit, and in the Boston suburb of Easton, a trick-or-treater dressed in a green Gumby costume tore down a "Make America Great Again" sign.
There's been no shortage of down-ticket misdeeds, either. In Rhode Island, former Democratic state Rep. Brian Coogan is accused of stealing a local rival's signs and faces larceny and conspiracy charges.
Although there's no national clearinghouse for violations, many states impose civil penalties with fines of up to $1,000 for removing, defacing or destroying political advertising.
