Both Democrats and Republicans are for large, strong, overarching government.
Probably a Libertarian president might make a difference and actually try to reduce the powers (and expenditures) of Washington, DC, and lower the burden of regulations. Try voting for Johnson. Unfortunately, chances to elect a candidate from outside the two big parties are about zero; Trump had to basically hijack the Republican party at its all-time weakest to become a real candidate.
If Trump gets in, he'll be able to do a lot of reputational damage with his rhetoric, but without the support of Congress, he'll be able to do very little in the way of actual legislative change. Mind you, it'll be interesting to see what he does when the debt-limit timebomb comes up again.
I'm not particularly in favor of a president whose goal is to "burn it all down" in the way the Libertarians want to, but executive power is wide reaching and almost unfettered and there is a whole hell of a lot a president can do.
I would say, as an aside, that we give too much credit to the president - you want to cut red tape? Start with the municipal government, and get them to ease off on zoning regulations. Go from there.
Furthermore, Republicans have long given up any pretext of wanting to reduce government control. No Child Left Behind, Sarbox, the entire mess that is Homeland Security, Defense of Marriage, "religious freedoms", increasing layers of drug regulation... it's just that Republicans want to regulate how people live their lives, instead of focusing on major corporations.
(Then, this doesn't even begin to get into the fact that many regulations are state level!)
