Trumps issue with trade is that he hasn't learned anything new about trade since the 80's.
90% of the issues he has brought up with regards to trade with Canada would have been addressed by TPP, but no can't have that evil Obama trade deal.
Canada aside, the TPP was a deal between the US and a bunch of poor nations that can and will do anything to undercut US business to secure reserve currency. Not to mention it provides its own governance with no oversight, just like the EU, removing autonomy from any countries involved in a dispute. It was a massive globalism power grab and one of the primary reasons I voted for Trump because he was against it.
Maybe you should actually research the shady as fuck history surrounding the TPP and what it was actually doing before just brushing it off as "durr trump didn't like it, must be good".
