WASHINGTON (Reuters) - When Pennsylvania holds primary elections on Tuesday, some election security advocates will be watching closely to see if more than 2,000 new voting machines acquired last year by Philadelphia and two other counties perform without glitches.
Philadelphia and Northampton counties first used the new “ExpressVote XL” machines in last November's local elections and will deploy them again in the presidential nominating contests and local races on Tuesday. A third county, Cumberland, will use the machines for the first time.
