A specialty license plate featuring a symbol that has become associated with the tea party movement is a big seller in Virginia. The Virginian-Pilot reports that nearly 21,800 vehicles in Virginia are sporting the “Don’t Tread on Me” plate. That makes it ninth in popularity among more than 200 specialty tag, and second only to the “In God We Trust” plate among those authorized in the last five years. The plate is based on the Revolutionary War-era flag featuring a coiled rattlesnake above the slogan. David Dwyer is a past chairman of the tea party in Norfolk. He says the “Don’t Tread on Me” plate is a symbol of frustration and disgust with government. He has the plates on two vehicles.
