Dick Morris, once a Clinton staffer and now a convert to conservatism, speaks the words which are obvious to all:
The question, however, is why? What's Bill Clinton's game? What does he gain by an Obama loss?
Hillary is a senior administration official. They don't get much higher than SecState. She's cobbled together a credible resume of governmental service reaching beyond the rather nebulous credential of having been First Lady. She's been at Bill's side in state government, she watched the executive branch from inside the White House, she's been a US Senator and now the manager of foreign policy for the nation. That's heavy duty regardless of your ideology.
She ran a bitter primary race against the Bamster in 2008. When he won, she was marginalized even as SecState. The Messiah was on the global apology tour and Hillary was visiting central African back-waters. She's still got the presidential jones unsatisfied.
The Bamster is not likely to swap her for Biden at veep. Bill is making sure that won't happen by dumping these clinkers on the Obama campaign. Obama doesn't want Bill around the White House catching the lime-light. If Obama gets a second term, Hillary will be history and that leaves her four years in the wilderness.
If Obama gets re-elected the country will be in such a mess by 2016 that the second coming of Christ wouldn't be sure of a Democratic election win. Hillary doesn't want to be seeking the Bamster's seat then. It works much better for her if Romney wins and she can campaign against a Republican president in 2016. Give her four years as the face of the opposition and she's a shoo-in. QED.
