Those who recall the age-old sayings about the rough-and-tumble environment of American political campaigns might not be too surprised to learn about what happened recently in Southern Maryland’s Calvert County.

Over the first two weeks of this month, campaign signs put up on behalf of at least two officeholders have been stolen. The signs are valued at more than $800, according to the county sheriff’s office.

Over the years, campaign signs have been stolen or defaced from time to time in many jurisdictions. But in an indication of perhaps more than common daring on the part of the Calvert thief, some of the signs taken belonged to Mike Evans, the county sheriff.

“It has been happening a lot lately,” said Mark Robshaw, a detective in the sheriff’s office. There are no suspects in the case, he said.

One of the sheriff’s signs was struck by a bullet, the sheriff’s office said. Adding to the concern about destruction of property was the fact that the shot was fired near a residential neighborhood, the sheriff’s office said.

Losses were also reported by Del. Mark N. Fisher (R-Calvert). There is a cash reward being offered in the case.
