John Glenn, center, poses with Senate Majority Leader Harry Reid of Nev., left, and Senate Minority Leader Mitch McConnell of Ky., on Capitol Hill in Washington, during a ceremony where Glenn received a Congressional Gold Medal. Glenn says he believes an “unattractive” elections process discourages the best people from pursuing public service. The 90-year-old Democrat is optimistic that good people will run for office but understands some might shy from opening their lives to intense public scrutiny, he told The Columbus Dispatch in a wide-ranging interview published Sunday, Jan. 8, 2012.
