I’m not gonna dispute your final conclusion, because it sure seems like it to me as well.
But ya can’t just say it’s all bullshit and bend over and take whatever they give you. We have to try anyway, as much as I think old Bushey is totally wrong on many issues (immigration, Iraq, foreign policy, etc.), I absolutely love the tax cuts he passed and the fact that our economy is running pretty well at the moment. That was actual ca$h in my pocket. So even though I didn’t get what I wanted on most issues, at least I got something for my vote. 
If there was actually a way to accomplish this, I would be right there. It’s tough to cast a vote for a third party candidate when you know they have no chance of winning. I would feel like I am just throwing my vote away. I will probably just suck it up and vote for the “lesser of two evils” just like last time.
