The only reason he was nice to him there was because Obama agreed to do what Bush and his advisors thought had to be done to save the economy they destroyed, in a few words sign and pass the TARP bill that among other things stabilized an economy that was shedding 750000 jobs a MONTH!
There was no time for partisanship and animosity then.
Obama is a genuine good person, which was his undoing with the republicans who made him a target, and so he wants to help this asshole to get a good grip on the reality of the office.
This is going to be an UGLY 4 years, with Bolton the neocon right winger jerk proposed for the cabinet, Dodd Frank reversed, etc., we will go RIGHT BACK WHERE BUSH LEFT US!!!!!!!!!
Plus all the racism and the ugliness, lack of integrity, misogynism, etc., that Trump brings.
F THAT!
