I wouldn't say Trump is outside the lobby system. I'd say he bypassed the lobbyist (aka the agenda people) and moved straight to the backers (aka the people with money who have agendas). About the only electorate Trump is worried about would be the Electoral College, I'd say.This is the Big Corruptor in US politics.
This is why Trump scares the establishment, I think.. It's not his antienvironmentalism or anti-migrant stuff or whatever. It's the fact that he managed to get elected largely outside of the lobby system. That means he can't be controlled by the usual mechanisms! He's beholden (almost) entirely to his electorate. That's unheard-of.
Sanders is the same kind of threat.
EDIT: it's not about issues, it's about power and access to power.
Edit: changed 'removed' to 'bypass'
