Cash for Ambassadorship vs Senate seat - I'm confused

Jake Tapper has a great article on how many big donors got rewarded with Ambassordships from Barry for contributing LARGE sum of money to his election campaign.   Here’s the link.


Can someone tell me the different when Barry get’s large campaign cash and gives these folks an Ambassadorship and then when Blago try’s the same thing with Burris and Jessie Jr…Blago get’s impeached and possible prison time?  Are not these the same…PAYGO!!!
