That's a very hyperpartisan spin you're applying here. I'll echo it as an exercise. You wish to shackle representatives to their party bosses and threaten them if they dare step out of line, no exceptions. You're acting as a mouthpiece of enforced conformity. Party corruption finds a hospitable place in your worldview.
This is entirely based on your argument that party identity, not abandoning past positions she ran on, is the measure of defrauding voters.
