Probably not gone on Leno, probably not made fun of the Special Olympics, probably not been so proud of himself for killing a fly, probably not wasted time on Guantanamo Bay, probably would have regretted his choice for VP
, etc. Although, Obama may have some feelings of regret as well with his choice.
I think he would have been harder on Iran and North Korea. Really, it is too early to tell. Unfortunately, with the Dems controlling everything, I think Obama is going to do a lot of things that end up upsetting many of his supporters who are not extremely far left by the end of this term. Really, with his power sort of unchecked, he has the potential of being up there as one of the worst presidents of all time. Bush included. Only time will tell.
