Colorado Dems: We caught James O’Keefe and his friends trying to bait us into condoning voter fraud http://t.co/tVUZFw5h5v via @motherjones

Last week, O’Keefe and two of his collaborators tried to bait Democratic field staffers into approving voter fraud involving Colorado’s universal vote-by-mail program, according to three Democratic staffers who interacted with O’Keefe or his colleagues.

Democratic staffers in Colorado recently came to believe they were the subject of an O’Keefe operation after campaign workers became suspicious about would-be volunteers who had asked about filling out and submitting mail-in ballots for others. Recently, the 30-year-old O’Keefe has targeted the Senate campaigns of Arkansas Democrat Mark Pryor and Kentucky Democrat Alison Lundergan Grimes by filming undercover videos of staffers or the candidate.
