Thompson's career in state government (which followed a brief, unsuccessful business career) was indeed long but hardly distinguished.
As a legislator, he was a hack known mainly for currying favor with lobbyists and getting an abandoned railroad in his district turned into a bike trail ("nawt that theh's anything wrawng with thaht"

). He was also called "Dr. No" for his talent, as minority leader, for blocking bills he didn't like.
As governor, after unseating a Democrat he dubbed "Tony the Taxer" (because Earl increased taxes to get the state out of a deficit and ended up with a surplus), Tommy presided over historic increases in both the size of state government (so much for "limited government") and in state spending, especially on roadbuilding contracts, many of which conveniently went to his cronies. So I'm sure he would've loved the Transportation post at the federal level.
His grasp of the English language is also about as good as W's, but at least it's better than Daley's dad's was. eek!
Anyway, if recent corruption scandals in Wisconsin's traditionally clean state government are, as some say, the product of too many career pols and not enough of the "citizen legislators" of old, I think the wheeling and dealing and logrolling of the Thompson years deserve at least some of the blame. I call it the Illinoisization of Wisconsin. frown
