And generally i agree with that.
For decades the GOP and Dem parties where trending towards the center right and center left, and for those who wanted 'real change' they would not really find much between the two parties. All the change was around the edges with the status quo continuing. Who was more 'right wing/corporate', Hillary or GWBJr???
And i supported the right and left fringes trying to make enough noise to shake the parties up.
But Trump and his promise to end the process of 'voter choice in gov't' represents a different threat that those who want 'change' need to recognize. This happened in Turkey and Erdoğan, effectively ended the democracy they had there. And it followed in Hungary with Orbán. Both of whom Trump idolizes and looks to as his model as to how to break the system from within.
I think most libertarian voters are so wedded to their 'rebel' image, that they would ignore the threat that would harm their goals, as much as anyone else.
This is Trump's last kick at the can. He needs to be defeated and then the old battles can be engaged.
