Was chatting with a friend of mine who has been on Tim Kaine's staff for several years now.
1) The friend is pretty pumped because he loves the show Veep.
2) Said that Tim only agreed to be VP if Hillary acknowledged that keeping any of Obama's people around or bringing back any of Bill's would look bad. Therefore encouraging her to take on some of his people.
3) If Tim's current staff don't want to work in the white house, Tim has promised to find them a nice cushy landing spot somewhere else in the government.
