Just breaking out of Ohio:
Courtesy of Marc Ambinder the Obama campaign has sent poll monitors out to challenge Clinton voters across Ohio who but those monitors are not properly credentialed.
They are only carrying a letter from Paul Tewes, Obama's Ohio State Director. It turns out that you need to be registered with a local judge to be "monitoring" polls.
From the Secretary of State's office:
To be allowed access to a polling location an observer must be duly appointed as an official observer and have an official observer certificate issued pursuant to R.C. 3505.21, which in part states: "Observers appointed to a precinct may file their certificates of appointment with the presiding judge of the precinct at the meeting on the evening prior to the election, or with the presiding judge of the precinct on the day of the election." Someone who wants to observe may present the attached letter in addition to the official observer certificate, but they must have the official observer certificate to legally gain entry.
These workers who are not legally in the polling locations are being thrown out by the Democratic Secretary of State.
The tactic is being compared to what the Ohio Republicans did in 2004. Since when did Democrats have to worry about other Democrats aggressively disenfranchising our core voters?
