Beware the one-party state
On Tyranny, chapter 3
Support the multi-party system. Defend and participate in true democratic elections. Run for office.
The system of checks and balances in America was designed to account for our known, real imperfections. A form of eternal vigilance.
Understand that some political movements are attempting to play a finite game rather than the infinite one. (See Finite and Infinite Games.)
Beware:
When the less popular of two parties suppresses voting, claims fraud when it loses elections, and controls the majority of statehouses.
End gerrymandering.
Paper ballots cannot be tampered with remotely and can always be recounted.
