I still see this as the political horse trading which was best exemplified when LBJ was in power in the Congress.  Neither of this agreement's participants are important or powerful enough to fit either Faustian role.   

Calling on Faust is just another way for advocates to demonize their opponents.  Yawn!

As far as Trump's 'policies', he is a chameleon;  he changes his 'policies' (such as they are) more often than most people change their socks!   Hillary has four to five sound bytes, Bernie has about three.  Trump tosses new ones out on Twitter almost hourly and sees what happens.   Some segment of the voting herd likes some of them and he repeats that byte for them.  

If they bomb, he is like the nasal  GPS lady "Recalculating!".
