These anti-Obama protesters outside an early voting polling place are clearing violating federal law:

No person, whether acting under color of law or otherwise, shall intimidate, threaten, coerce, or attempt to intimidate, threaten, or coerce any other person for the purpose of interfering with the right of such other person to vote or to vote as he may choose, or of causing such other person to vote for, or not to vote for, any candidate for the office of President, Vice President, presidential elector, Member of the Senate, or Member of the House of Representatives, Delegates or Commissioners from the Territories or possessions, at any general, special, or primary election held solely or in part for the purpose of selecting or electing any such candidate.
