Because so called conservatives keep electing moderates and liberals because winning is more important than winning with people worth voting for that adhere to the Constitution. If you voted for Romney for example and still defend that idiocy of ‘lesser evil’, you would be part and parcel of why we are in this mess and why we don’t get constitutional people in office.
Truthfully where I live Romney would get less votes than Karl Marx so out of some deluded notion of what I could actually say with my vote I did check off Romney after promising myself I would not. My bad for sure.
We have very little to argue about and that is mostly for fun but I will vote for Trump not because I am enamored by him but because he will be the opponent of Hillary or whomever the Democrats put forward.
