VANCOUVER, Wash. -

Clark County supporters of President Barack Obama and Democrats have been getting tomatoes thrown at them.

The Columbian reports the Vancouver Education Association saw its third episode of a tomato attack on Monday.

Vancouver Education Association president Courtney Eyer said police think the suspect is a man who rides a bicycle and has been throwing tomatoes at buildings where campaign signs for President Barack Obama have been posted.

Earlier this month, someone distributed a letter in the Minnehaha that stated a few people threw tomatoes on the roof of a neighborhood home that had an Obama sign in the yard.

Republicans have also seen their share of vandalism.

Clark County GOP Chairwoman Stephanie McClintock said someone threw rocks through a glass door and windows at the county Republican headquarters in Hazel Dell last week.
