Corruption in Illinois, continued.

There is something stinky about this Illinois Governor investigation.
The reports I hear and see indicate that Blagojevich has been under investigation for years now because he has been suspected or corrupt behavior for some time.
Apparently, there are wiretap recordings of Blagojevich talking at length to different people about how this was a gold mine, and he wanted to get rich off of it (I am referring, of course, to appointing a replacement for Barack's vacated Senate seat).
It appears that some of the potential buyers were actually identified, such as, Jesse Jackson, Jr., who allegedly offered a half million dollars in campaign funding for Blagojevich with a promise of a million more later.
King Barack says he never talked to Blagojevich about this, but if that's true, why is the Governor heard on the wire tapes to say "All Obama offered was gratitude"? If he didn't talk to Barack, did he talk to one of Barack's loyal minions?
Why would this U.S. Attorney, Patrick Fitzgerald, run this investigation for so long and then stop it right before he has the second rat in the trap (referring of course to the person who might actually purchase the appointment from the governor)?
Isn't the buyer just as crooked and corrupt as the peddler?
Were they afraid that they might have to arrest someone close to the new President? Rahm? Axelrod? or the new President?
Why would an investigator do all of that work for all of that time, showing that much patience, and then spring the trap prematurely?
And why have they let Jesse Jackson, Jr., off the hook so quickly and completely when he is specifically named as making an offer? Do they not actually have Jesse Jr's voice on any of the taps?
It seems to me that they had the seller, so they really just needed to exercise a little more restraint and patience and they would have had yet another corrupt politician in their grip.

Side note: I heard a report on the Wall Street Journal radio station that a poll of Illlinois voters showed that something like 82% think that Blagojevich should immediately resign his officer over this. But further, they said that about like 85% of the voters polled said that Blagojevich was doing a poor job governing the state. How did this guy get elected in the first place?

Side note #2: This appointment of Tom Daschle as the Secretary of Health is a little frightening. Supposedly, he is to be the front man for the health care reform. This is the guy that got soundly defeated in his own state by a Republican challenger because he was such a stark raving socialist. The people of South Dakota had enough of that representation. But now, King Barack puts him on the cabinet to inflict him on the entire nation? The guy can't win in his own state, so he gets a cabinet seat?
