Everything Hitler did was legal.
Sometimes after the fact, but always codified to be so.
Republicans have control of the Presidency, House, Senate, Supreme Court, most governorships, all or part of most state legislatures, and a significant number of federal judgeships.
Believing that in two or four years we will be able to change that electorally is to not understand what it is the Republican Party, its allies, and supporters are intending, and their plans to achieve their goals, legally.
