Well, to be fair, we have a pretty good example of what life will look like under Democrat rule.
The bonfires sure look pretty but, frankly, marshmallows toasted over a burning tire end up with a funny taste.
Is this not all happening now under Trump's watch?
You have to understand Trumpists' rules:
If an R is in office and something good happens, the R gets credit.
If an R is in office and something bad happens, the Ds get the blame
If a D is in office and something good happens, the Rs get credit.
If a D is in office and something bad happens, the Ds get the blame.
This is why Bush could turn a surplus into a 440 billion yearly deficit, then allow deregulation to blow up a mortgage bubble, pass TARP, hand Obama a 1.4 trillion deficit, and all that be Obama's fault.
This is why Obama could get stimulus passed, get ACA passed/etc, and bring that huge deficit down to ~550 billion/year, give Trump the "best economy ever", and Trump to get credit.
This is why Trump can take that, double it with tax cuts for the upper crust, lie and deny about COVID getting nearly 200,000 Americans killed, deliberately make things worse by sending feds in to kidnap random protesters to intimidate them, and that's all Democrats' fault.
