BATON ROUGE, La. (AP) — Another elections technology firm is objecting to the terms of Louisiana’s voting machine search, accusing the secretary of state of trying to manipulate the bid process to benefit its current contractor and raising echoes of the dispute that derailed efforts to get new machines three years ago. Election Systems and Software filed a formal protest with Louisiana’s procurement office about the criteria that Republican Secretary of State Kyle Ardoin, the state’s top elections official, is using to replace 10,000 Election Day and early voting machines. The Nebraska-based voting system vendor, known as ES&S, said Ardoin’s bid solicitation will limit the state to choosing a “system virtually identical to the current system.” ES&S said it’s impossible for any company to meet the criteria except for Louisiana’s current contractor, Dominion Voting Systems.
