ATLANTA — Georgia lawmakers are considering replacements for the state's touch-screen voting machines that were adopted statewide 15 years ago and that have been criticized because they don't produce a paper trail. The state House Science and Technology Committee heard on Thursday from representatives of three different voting technology companies. "We're just trying to understand what options the state of Georgia has," said state Rep. Ed Setzler, a Republican from Acworth who chairs the bipartisan panel.
