I don't think it will do much for Hillary's future presidential plans, though.
Clinton isn't a fall guy and didn't even break a law that I can see (unless it can be determined that he was aiding and abetting a criminal act). He was merely an agent of the administration..a go-between.
The crap about feeling out Sestak regarding his seriousness (as to running)...it doesn't take someone as important as Clinton. Anyone who knows Sestak can do that.
And the unpaid aspect of a promised job is irrelevant because any job with the president has a great deal of future value.
In the final analysis, a crime was committed or this matter would have been handled quickly when it first arose. There's no need to stonewall over an innocent exchange.
