Modesto police are looking into whether vandalism at the Stanislaus County Democratic Campaign Headquarters over the weekend was politically motivated.
Party leaders say vandals threw rocks through five of 11 windows on the building and spray-painted "RAAN" on the wall. Regional director Gary Robbins told KXTV that the initials stand for "Reds and Anarchists."
Police say the attack happened sometime between late Friday and early Sunday. The windows displayed signs for Democratic campaigns, including that of Sen. Barbara Boxer.
No nearby buildings were damaged, and no arrests have been made.
Volunteers spent Sunday cleaning up the mess, putting off their campaign work with just four weeks left before the election.
