What in Trump's background makes you think that he's honest with his platform?
It's pretty obvious that if he gets elected, he's going to run the country the same way he's run all of his businesses: He makes a bunch of unrealistic promises, siphons money from the investors/customers into his own pockets, and then declares bankruptcy. I mean, seriously, do you think he's telling the truth when he says he's going to build an impenetrable wall along the whole southern US border? His plan is to pocket the estimated cost of the wall, and that'll be the last anybody ever hears of it.
You're right that Hillary Clinton lies about as much as the average politician, so we need to look at her history as well. Based on her past record: If she's elected, she'll probably try to move things a bit towards the left but mostly keep the status quo in place. Of course a lot of this depends on what kind of Congress she winds up with. But if Trump wins, he'll be guaranteed a Republican Congress that won't have the courage to provide any meaningful resistance to his schemes.
