That's the most naive thing I've heard in a long time, I'm not quite sure where to start.

If they’re in power and let the government, they get blamed for it.

Demonstrably not true, Republicans love this tactic because people tend to AT BEST blame both sides. Voters are incredibly misinformed.

Let the government fail. If it’s in a position where one political entity gets to hold it hostage in perpetuity, it’s functionally unsalvageable and broken by design

I don't know how you could get to this conclusion. Let the government fall, because by attempting to break it, Republicans have automatically made it just as bad as if it was already broken? That's an incredibly dumb statement.
