The truth is Democrats aren't going to do shit to "save democracy," and anyone who thinks or thought they were is delusional.
Notice, the Democrats never ran on how exactly they were going to save democracy. The reason they didn't is that saving democracy is incredibly unpopular. If you actually want to save democracy, you have to pass very unpopular laws.
Mainly, you need to strip the presidency of all the emergency powers Congress has given it over the years, dismantle the post-9/11 security and surveillance state, and disband ICE.
Here is the problem. Doing any of these things will literally get Americans killed. If you dismantle the unconstitutional mass spying apparatus, inevitably, eventually, there's going to be some terrorist attack that occurs that that spying could have prevented. If you disband ICE, inevitably some person who happens to be an illegal immigrant is going to kill some white woman, and it will be found out that ICE would have deported them before it happened.
In these cases, I would argue that the deaths are worth it. I am absolutely willing to trade some safety for freedom. Freedom is worth fighting for; it's worth dying for. It's worth seeing innocent people die for it.
That's the core problem. The tools of a dictator are also the tools of ordinary law enforcement. If you strip away the dictator's toolkit, you also disempower law enforcement, which means some otherwise preventable crimes will happen. And your political opposition can latch onto those few rare cases and crucify you with them.
This is why Democrats cannot save democracy. Ultimately, they are complete cowards. Saving democracy requires courage and conviction. It requires a politician to look the voters dead in the eyes and say, "some of your children are going to die because of this bill I am proposing, and that is an acceptable loss I am willing to pay to ensure our children get to live in a democracy."
I've never seen a Democrat running on that kind of message. But that's what it would take to actually save democracy. And this is why it will not be done.
