Kind of off topic, but Bunning is retiring because the Republican Party refused to endorse him and directed all fundraising efforts in Kentucky towards a more conservative candidate. Essentialy the Republican Party is paying Bunning back for not voting lock step with them. This is basically him deciding he's still in the Senate for now, and he can do whatever he wants and say what he wants, and since he's a republican, it will reflect on them. So it's merely a tit-for-tat thing. Still, it's moronic.
