So, by this logic, we merely need to decide whether we wish to elect the politician who meets the needs of Wall St., the prison industrial complex, and war profiteers. If so, we vote for Clinton, because she is extraordinarily favored by those interests. As you note, a politician could be entirely honest and sincere in their beliefs, and still be supported by a corrupt system...so long as their sincere and honest beliefs happen to coincide with the needs of the corrupting parties.

I'm not particularly political, but Clinton is a particularly unnerving example of the kind of politics I find distasteful and a symptom of our broken democracy.
