A man who was being paid to register voters by the Republican Party of Virginia was arrested Thursday after he was seen dumping eight registration forms into a dumpster. Colin Small, 31, was working as a supervisor as part of a registration operation in eight swing states financed by the Republican National Committee. Small, of Phoenixville, Pa., was first hired by Strategic Allied Consulting, a firm that was fired by the party after suspect voter forms surfaced in Florida and other states. The owner of a store in Harrisonburg, Va., told a local television station that he became suspicious when he saw a car with Pennsylvania plates dump an envelope in back of his store. He recovered the envelope and alerted authorities. “He made a mistake and he’s being charged with it, which we fully support,” said Sean Spicer, a spokesman for the Republican National Committee. The committee paid more than $3 million to state committees to finance the get-out-the-vote operation.
