Would you want to be Vice-President if Bill is in the White House all day and sleeping with the President at night? Naah! At the prospect BO would remember Cactus Jack Nance Garner's -- FDR's Vice-President --1933-41 -- statement that being VP is "not worth a bucket of warm spit." (The New Yorker, March 22, 2004, claims that he actually said "warm p*ss.")
Garner's dictum did not hold with Bush-Cheny and some other recent occupants, of course, but, if it were Clinton-Obama, it might become true again -- in fact if not in outward appearance.
But, on the other hand, politics makes for strange bedfellows, so Hillary-Barack in bed could happen (we refer here to "political" bedfellows, of course -- a clarification necessary whenever Bill is in the vicinity, since he has had some strange "non-political" bedfellows).
Hill and Bill playing second fiddle to Barack? Naah!
