So, the United States is no longer a democracy. If a president wants to remain in power despite losing an election, they can, as long as they get the right people behind them, which is how every dictatorship works. What makes democracies different is that they have laws to stop that, and the supreme court just ruled those don't apply to the president. There is no mechanism to stop them. You can say impeachment, but the results of an impeachment against the president are as much of a foregone conclusion as a North Korean election. The trappings of democracy does not unmake a dictatorship.
We're no longer a democracy, and the only way we can ever return to being one is if we elect a string of dictators who feel disinclined to push their power as far as it can go. If we can do that long enough to get this decision overturned, we can have our democracy back.
