WASHINGTON (AP) — A House task force voted Friday to end an investigation into a disputed 2006 Florida congressional election after extensive testing showed that touch-screen voting machines likely worked properly.

Democrat Christine Jennings called for the congressional investigation after she lost the District 13 seat to Republican Vern Buchanan by 369 votes. She suggested Sarasota County's touch-screen voting machines were to blame for the more than 18,000 ballots that did not register a choice in the contest.

But the U.S. Government Accountability Office, which conducted extensive testing of Sarasota County machines last year, said it was satisfied that votes were counted properly. It's more likely, the investigative arm of Congress said, that voters skipped the race, either intentionally or by mistake, on the ballot.
