Protesters smash window at Obama's campaign office in Oakland

Since the AP didn't report on protesters' political affiliation, does that mean they were dissatisfied left-wingers.

OAKLAND, Calif. (AP) — Police say protesters marching through downtown Oakland smashed a window at President Barack Obama's campaign office.

Officials say the window at Obama's office at 16th Street and Telegraph Avenue was broken as more than 100 protesters marched around 9 p.m. Friday.

Police say the marchers also smashed several car windows.
