LAS VEGAS — Some voters in Boulder City complained on Monday that their ballot had been cast before they went to the polls, raising questions about Clark County’s electronic voting machines. Voter Joyce Ferrara said when they went to vote for Republican Sharron Angle, her Democratic opponent, Sen. Harry Reid’s name was already checked. Ferrara said she wasn’t alone in her voting experience. She said her husband and several others voting at the same time all had the same thing happen. “Something’s not right,” Ferrara said. “One person that’s a fluke. Two, that’s strange. But several within a five minute period of time — that’s wrong.” Clark County Registrar of Voters Larry Lomax said there is no voter fraud, although the issues do come up because the touch-screens are sensitive. For that reason, a person may not want to have their fingers linger too long on the screen after they make a selection at any time. “Especially in a community with elderly citizens (they have) difficulty in (casting their) ballot,” Lomax said. “Team leaders said there were complaints (and the) race filled in.” At any time, voters can go back on the screen and review their selections. They are also allowed to make changes and encouraged to double-check their ballot on screen and on paper before it is cast. Lomax said claims the machines were altered in any way were “patently false” and said at no time did any of those voters report the incident to staff at their polling location. “In fact, although over 160,000 people have voted early in Clark County, those allegations that have been made have gone directly to the media as opposed to election board officers,” he said.
