A significant percentage of leftist politicians are always just a slight nudge away from becoming unhinged: Obama, Pelosi, Turban, Hillary and Slick, Dingy Harry. Far too many to mention.
Absolutely, all are nut cases. But then, so are many Republicans in congress. I think they must all be on uppers. Legal, prescription uppers like Provigil, which is almost but not quite listed on FDA Schedule II (controlled substances ... "the drug may lead to severe psychological or physical dependence") or on Adderall, the amphetimine which is on the list.
After a day on crazy-making uppers, they of course need Oxy to sleep at night. And we have the government that we voted for. And BigPharma bought.
