IMHO many good people take a look and see what’s in store for them from the GOP-E, DNC and their bootlicking media and simply decide it’s not worth it.
Unfortunately its not just politicians. Too many conservatives are unwilling to forego their current comforts to take a real stand for what’s right.
My congressman told me that the tea party came out in force to elect him, then they went home and he hasn’t heard a peep out of us since.
