Recently, group of Republicans actually protested an early voting location in North Carolina:
As you can see from these videos, no one held anything back. People were shouting about Obama's acknowledged cocaine use as a young man, abortion and one man used the word "terrorist." They also were complaining that Sundays are for church, not voting.
And I guess protesting is OK? These folks are going beyond the McCain campaign's previous attempt to demonize ACORN and doing something that looks very much like voter intimidation -- especially disturbing considering the history of racist violence surrounding voting in the South.
