I can already see one major flaw.
Democrats will only want to kill Republican politicians and then Republican voters and the Libertarians and Constitution party members. Then they'll turn on each other.
Republicans will only want to kill or imprison all Democrats and a bunch of Republicans politicians and then stop.
I don't support the Democrat plan. It's too much like the French Revolution.
The Republican plan is much better but the best solution is to remove them all, and their staff, from office and never let them step foot in any government building ever again, not even for a visit.
Actually fire about 95% or more of all government employees, except for military. And put a permanent hiring freeze on the government.
