“Charges of voter suppression are flying in Pasco County, Florida. According to the County Supervisor Brian E. Corley, his office is being overwhelmed with hundreds of voters alerted by robo-calls from Organizing for America that early voting started today. OFA is the re-election organization for President Barack Obama. Early voting does not begin until Oct. 27. Some voters have even begun showing up at the office, only to be turned away.”

Of course this is not voter “suppression.”  If the Obama campaign makes robocalls giving people the wrong date of the election, that isn’t illegal.  There is no federal law violated when you give someone the wrong election date.
