Republican presidents traditionally view the Vice-Presidency as life insurance. They choose the most outlandish, frightening people as their Veeps. Even the most insane lunatic would think twice about pulling a trigger that would make Dan Quayle or Dick Cheney commander-in-chief. If Richard Nixon hadn't lost Spiro Agnew because Agnew got caught being a petty thief Congress would have blanched at the prospect of impeachment and Nixon would have completed his second term. Democrats, conversely, believe that "heartbeat from the Presidency" malarkey. They choose intelligent, competent Veeps (Gerry Ferrero excluded).
I am seriously prejudice having watched Jonathan Demme's remake of The Manchurian Candidate recently. I believe Obama's life won't be worth a plug nickel if Hillary is standing at his right shoulder. It would be too tempting for one of her Talk Left Hillbots (new link) to rescue the nation from that arrogant boy Obama. And, given the Secret Service's Klanish tendencies, I can't expect them to move very fast to stop it.
Keep your friends close, and your enemies closer. ~ Sun-TsuOn the other hand, the only way to keep Hillary from sabotaging the election (so she can run again in 2012) would be to have her on the ticket. It's a conundrum.
My advice is that Barack learn to enjoy the feeling of Kevlar against his skin and, every so often, he should insist Hillary stand to his left.
UpDate: Re: MSNBC: It's one thing for me to muse uncomfortable about an Obama assignation. It is quite another for Hillary Clinton to speculate that if only Obama were gunned down like Bobby Kennedy it would open the way for her nomination. Kevlar won't be enough if Hillary is the Veep. Barack will need several food tasters, a half-dozen body doubles, and immunization from every imaginable tropical disease.
