"I was referring to DeLay's decision to resign because he couldn't win re-election."
DeLay did not resign because he could not win re-election. He resigned because he has been indicted and could not get a trial in time to run again. He did not want to run while under indictment and decided it was best to let someone else try to win the GOP.
I am relying on DeLay's own statement that his candidacy was putting the TX22 seat at risk. I don't think DeLay lied about this, but I respect your contention that he did.
