Prediction: He won't retire. He will run again next time around and he will be re-elected by an even greater margin since he is such an honest guy.
Half of congress should be under arrest right now as far as I am concerned. Dodd, and Pelosi and Fwank are all vying for top spot on that list.
No, Dodd will be re-elected because the parasites outnumber the hosts. As long as he and the rest of the rats keep delivering "free stuff" to the parasites (the Democrat "base") in exchange for their votes, the parasites couldn't care less about things like honesty, integrity, good character, America, etc.
