Like a rat trying to escape the trap, Democrats are squealing in pain over their predicament. Notice that the ethical issues on the GOP travel expenses from only a few weeks ago are all past tense? It's because too many Democrats were caught in the web of their own making.
I agree with another post too. It may turn out all this is an effort to sanitize Hillary's run for office in 2008. But, it also has the potential of helping them win in 2006. (Another aspect of showing how desperate they are. Every time Democrats fail to gain seats, they get further behind and less successful.)
I like the sanitization theory, could be the truth.
