WICHITA, Kan. (AP) — A Wichita State University mathematician says she has seen enough odd patterns in Kansas election results that she thinks it's time to check the accuracy of some voting machines. But Beth Clarkson says government officials have been reluctant to provide her with the records she needs to conduct an audit. The Lawrence Journal-World reports that Sedgwick County election officials refused to allow computer records to be part of any recount, instead telling Clarkson if she wanted them she would have to fight for them in court. Clarkson says an audit is important because of national concerns about the voting machines that thousands of Kansans use to cast their ballots each year. She adds that she noticed some suspicious patterns after the November elections and wants to find out why.
