This is, in essence, the Clinton Gang versus Capone's Chicago boys, and BJ Billy has already been impeached once. It isn't unthinkable - impractical, maybe, but not unthinkable because they're thinking about it.
BJ Clinton survived impeachment, which has made it easier to re-create him in the historical record. What will remain permanently are his escapades with his young intern, which will never disappear.
Obama will be much harder to tie to any scandal; he isn’t smarter than BJ, but the men operating his teleprompter are - they have taken “Clintonesque” responses to a whole new level. Obama’s problem is simply that this country’s economy has ground to a halt, and he’s fiddling while we degenerate into Third-worldliness.
