The Clinton’s hate Obama, the only reason why she accepted the Secretary of State job offer was to have some foreign policy experience going into 2016(When she will probably run for President again) no way would she accept the VP slot from Obama
And as mentioned up thread, she’s going to be out of the country during the Dem convention.
Clinton staying as far away from Charlotte as physically possible
Secretary of State Hillary Clinton, as a sitting administration official, does not have any role at the Democratic National Convention next week in Charlotte. But she seems to gone out of her way to avoid the festivities, as she is traveling this week and next to the Cook Islands, Indonesia, China, Timor-Leste, Brunei, and Russia.
"The Cook Islands this year are the hosts of one of the most important institutions of the Pacific called the Pacific Island Forum," a senior State Department official said Thursday. "It's a group that meets yearly with a number of working groups. It's been in existence almost half a century; it's very significant."

In other words, “So long suckers”. “See ya in 2016”. Say what you will about Hillary, she’s not stupid. She sees the writing on the wall and is trying to distance herself from Obama. (That and there might be booze and scantily clad dancing girls on the Cook Islands ;), )
