Questions continue to surround whether Tommy Thompson will make a run for the U.S. Senate. UW-Madison political scientist Charles Franklin says there are increasing signs the former Wisconsin Governor will enter the race.
Thompson is Wisconsin’s longest serving governor, who left in 2001 to join the Bush administration.
So far, Middleton businessman Terrance Wall is the only major GOP challenger to incumbent Democrat Russ Feingold.
Franklin says it’s not clear how serious the speculation of a Thompson run is, but the possibility is starting to attract notice following reports that campaign donations are being sought.
