Impeachment charges will only happen if Dems are leading the charge. And unless O hits rock bottom, the Dems will not subject one of their own to another impeachment event.
There is no rock bottom deep enough for the Dems to participate in an impeachment of a Dem President. Period.
Clinton sold forbidden US technology to the Chinese communists for campaign cash. The media and the Dems knew it. They covered it up, lied about it and when confronted, dismissed it. That was *high treason* and it wasn't sufficient. And Slick Willie wasn't even half black.
