Finally, absolutely nothing the man has said makes me think that any of the issues that concern intelligent people about the TPP will be addressed.
So, you're right, I guess we can feasibly work out another better trade deal, it's possible he'll grow an inoperable brain tumor that will suddenly turn him into a rational human being, but realistically, no, Obama's TPP was better than anything we're going to get in the next four years.
By the time a sane president is elected, I expect it will be too late to get control over the Pacific. China doesn't suffer from uninformed white trash idiots weighing in on foreign policy with countries they can't locate on a labeled globe, so they aren't going to suffer a similar setback. They will set up deals that will cement China as the major power of the area for the rest of our lives. Which, given the idiocy of voters here, might be a good thing.
