Status quo vs. something different. The status quo is that Obama/Hillary have destabilised countless countries, and are sabre rattling against Russia, possibly leading to an eventual nuclear war.
By contrast, Trump is promising less wars, less interventionism, and otherwise is a relative wildcard with a penchant towards pragmatism and deal-making.
I'm not American, but on paper, it looks like Trump would be an improvement as far as world stability goes, I'd vote for him based on his policy concerning Russia alone.
The Clinton/Bush/Obama dynasties have not made the world a better place, have not contributed to anything positive IMO, and judging by all the leaked emails, they're all corrupt as well.
