On a conference call with reporters, Obama campaign attorney Bob Bauer discussed concerns over how the Nevada caucuses were conducted Saturday.

According to state law, “In order to participate in the Nevada State Democratic Party Caucuses, attendees MUST be in line, or signed in, by noon. At noon, Presidential Preference Cards should be given to any person in line, and after that point, no Presidential Preference Cards should be given to any new arrivals, as they will not be allowed to caucus.”

The Obama campaign claims to have received a “significant amount of reporting from precinct locations that doors were closing well before noon, many times as early as 11:30.” The campaign also described reports that a manual had been distributed to Clinton precinct captains that said that registration deadline for caucus ended at 11:30. They had an “unusual high number reports that the Clinton campaign was insisting” that this be enforced.

After setting up a hotline for voters to report irregularities, the campaign says it has received “hundreds of calls” from “all over the state.” Although many of these complaints came from Obama voters, the campaign said they want to make sure that no voter, no matter who he or she supports, is disenfranchised.

Other than the number of calls, the campaign doesn’t know how pervasive these early closings were and stressed they “are not calling the results into question at all.” They will notify the Nevada Democratic Party and request that they look into the matter along with the DNC to “collect all the relevant facts.” The Obama campaign stated that they wanted to make sure “this sort behavior was highlighted.”
