Wisconsin Assembly Speaker Jeff Fitzgerald will be officially announcing his bid for US Senate today (Tue). His spokesman John Jagler tells us that the Horicon Republican will be outlining his plans throughout the day with a variety of media outlets. Fitzgerald, a former Beaver Dam alderman, will join us for a brief segment at the beginning of WBEV’s Community Comment at 12:40pm. He filed paperwork with the federal government last week that allows him to raise campaign funds. He is among four Republicans seeking their party’s nomination for the Senate seat to be vacated by the retiring Democrat Herb Kohl next year. So far, Congresswoman Tammy Baldwin of Madison is the only Democrat running.
