You are quite correct. There isn't a thin dime between Trump and Clinton in terms of effect or ethics.
You are right, there's not a dime difference.
They agree on everything except:
1) Border control and immigration.j
2) Strengthening the military
3) Rebuilding coal and fossil fuel industries.
4) Abolishing the Iran deal.
5) Appointing justices "like Scalia" as Trump said...Clinton wants justices like "Sotomayor".
6) Oil pipeline to Canada
7) Clinton was more taxes on corporations, Trump wants far less.
8) Clinton wants to raise individual taxes, Trump wants to hold the line and/or cut.
9) Clinton wants to turn virtually every illegal into a citizen, Trump wants to deport millions
10) Trump wants to get out of crappy trade deals and force corporations back to the US, Clinton thinks our trade policy is just great.
11) Virtually every other issue imaginable.
While you may think Trump to be duplicitous and uncommitted to the above positions, he WILL be tied to them as he has made them the epicenter of his campaign. A president cannot walk away from such things, particularly when his only base of support in governing will come from the GOP members of the House and Senate. So while you may doubt him, he will have no choice politically but to hold tightly to all those positions...so his personal veracity will be controlled by political necessity. Hillary on the other hand, will work with 110% ferocity to ensure everyone of those items on the above list are imposed on all of us with a liberal tenacity that will shape the SCJ for a generation, remove your gun rights...perhaps permanently, weaken our national defense, proliferate abortion including the heinous "partial-birth" procedure, and ensure the perpetuation and triumph of the liberal cultural ideal and political correctness for the rest of our lifetimes.
Any idiot who can't see the difference between these two on policy and purpose, is being a willful fool who lacks the maturity to accept that in the contest between two evils, one of these evils is vastly worse than the other. But hey, continue on reassuring yourself with these simplistic/childish declarations that they are "both the same". It helps some to justify acting like a spoiled child, and will ensure the hegemony of extreme Leftist governance under the purview of Mrs Clinton.
