"Then why did Foley resign?"
He resigned over the IM's.
Yeah, so? My point is, it's over, Foley resigned...Move on!
What you've pointed out is something interesting, but it's means nothing. If Foley was fighting the charges and Hastert didn't approve of investigations then this would have legs, but this is a moot point now. I don't mean to say that you bringing light of this is wrong or not justified, it's just moot now.
The Repubs need to move on to different issues, go on OFFENCE!
God forbid, "I" actually confuse anyone! ;-)
