We haven’t heard the last of tea party firebrand Joe Walsh. The one-term former GOP congressman, who was defeated for reelection last November by Democrat Tammy Duckworth, may be headed for a new career as a radio talk show host. Walsh is close to signing with WIND-AM (560), the Salem Communications conservative news/talk station, to host a Monday-through-Friday nighttime talk show. If it’s a hit, insiders said, national distribution could follow. Walsh said last month he’s been encouraged to run for Dick Durbin’s U.S. Senate seat in 2014.
