I don't see anything as a missing option. Reality is that we will either have Trump or Clinton. If we had alternative voting it may be different, but probably not. People upset with the way the country is going should be voting Trump. People happy with the direction should vote Clinton. They both have major personal issues, and in my opinion one greatly outweighs the other, but the policies they are presenting are very different and will move the country in very different directions. READ THEIR PLATFORMS!
Clinton is more Government, more entitlements, higher taxes (sorry but you can save the bullshit, all taxes will go up), and the Government will overtake the private sector as the main employer in the US. Obamacare will become single payer so we will have nationalized healthcare. Lobbying and Corruption won't get any better, and will probably get worse. We will see increases in immigration of all sorts, less concern over border security, and less transparency from your Government. The military will either maintain or see further cuts. Energy will be a problem and become insanely expensive. But hey, we can say we're "green". Supreme court judges will come from the PC Police crowd, notice Clinton did not name anyone or anything to do with Constitutional rights when asked questions on her potential candidates.
Trump has put out a completely different platform. Border control and tighter immigration, lower taxes to keep business here and penalties for the crap like Disney did in offshoring all their workers. Last week he released a good chunk of a 100 day plan which would reduce corruption and the impact on lobbying. (term limits on Congress/Senate, reclassification of many jobs as lobbyists [current loopholes "consultants" and "advisors"], and a 5 year moratorium on being a lobbyist after leaving Government jobs. He wants to reduce regulation on industry and energy, which has impact on "green" but increases domestic economy. Military gets a boost, which in my opinion we need. The supreme court gets conservative appointments already released, and they are historically minded candidates.
There are wild cards too, but we can save them for later. Claiming Trump won't live up to his platform is like saying Hillary will live up to hers. In both cases there are questions.
