Here are a few paragraphs from a Breitbart story today.
The wife of Vice President-elect Joe Biden let it slip that her husband had a pick of two jobs in the Obama administration.
Jill Biden said President-elect Barack Obama gave Biden the choice of being secretary of state or vice president.
.. … … ..
The vice president-elect tried to hush his wife as soon as the words came out of her mouth, with a loud "shhh!"
Jill Biden said the job of vice president was better for the family, because as secretary of state he would travel too often.
Here is a post from this blog from 8-23-08 titled, 'Why Biden?'
Why indeed. Obama is not necessarily planning to keep him as a running mate. But he might be useful at present. Hillary Clinton's supporters are an unhappy lot and many would like to dislodge Obama during the convention. Many super delegates must be skittish looking at Obama's poor performance and slippage in the polls. His hypnotic worship of Europe and China will only serve to continually drive mainstream voters away from him.
Putting Biden on the ticket can get him past the dangers of the convention. Biden has long standing and deep ties to many super delegates, labor leaders, Washington insiders and Democrat party insiders. Biden will insulate him against any possible revolts at the convention.
Then, after the convention Obama could replace Biden with someone more to his liking. And Biden would then join the many people that Obama has been forced by convenience to throw under the bus.
I submit that Obama approached Biden and asked him what it would cost to get around the super delegates and Biden went back and forth between State and VP before sealing the deal.
