I believe we’ll learn tomorrow that Biden was Obama’s second choice. Everybody else was tied for first but they didn’t want the job.
I'm sure you're aware that there is a specific choreography to this dance.
Initially, conversations are done via both of the staffs of the parties involved. Questions are hypothetical, such as.........
If our candidate were to ask your candidate to be his/her running mate, would your candidate accept?
If the answer is no, then everyone can say with some degree of honesty that so-and-so never asked so-and-so and so-and-so was never asked by so-and-so.
That way, no one will be embarrassed..........
unless of course you end up with Joe Biden as your running mate.
