BillBoy,
You were not paying attention. Fitzgerald was not going to win re-election by any stretch of the imagination. He angered people of all stripes because he was so independent. For example, he was the one who nominated the other Fitzgerald (a NY Democrat) for US Attorney. You know, the guy who persecuted Rove and Scooter Libby.
If Fitzgerald did not have family money, he would have hard a hard time beating Mostly Fraud because he was not getting a lot of financial support from Illinois conservatives and Republicans. After all, he was not a telegenic or dynamic figure (whiny voice and all).
IMHO, he was a good senator, and I fully agree with his libertarian positions.
Your incredulousness is either disingenuous or reflects your willful ignorance. (Probably both).
