Are Democrats truthful about anything ?

They are never truthful. They are a bad combination of evil and stupid.

"A little leavening leaveneth the whole lump", and "he that is faithful in little, is faithful in much". If you'll lie about anything, it'll become a character norm. Kinda like stepping over the line of going out on your spouse and is not akin to changing cultural norms where the issue of deceit or a lie becomes a subjective preference.

There is a sickening (sub-conscious) feeling of guilt and of ultimate judgment when one lies to oneself, albeit many become comfortable with that and "sear their conscience with a hot iron". It's the road to perdition, and this Nation is on it as politics has become a struggle for which side employs the cudgel of power as opposed to an honest debate/argument re upon what basis the power should be justly employed.

Authoritarian governance is never pretty or painless and herding cats always gets ugly when the cats are not convinced of the honesty of those doing the herding.

Honestly, a lot of this is driven by over population, IMO; I remember that experiment with the rats as their population grew...so did the violence. Something big is coming, and this coming year will likely be pivotal.

The public is being systematically gaslighted by those controlling Big Media and Big Tech.

Congress could easily fix these problems ….. if they weren’t being provided indulgences to look the other way ….

The truth is not in them, nor any other professional politician.

No, as everything is relative. They lack a true North.

A Democrat voter is a sheep, just following the lead of the more dominant sheep...you know, the loud-mouthed dumb-asses like Maxine Waters, Chuck Schumer, Eric Swallwell, Jamie Raskin, Barack Obama, Hillary Clinton, etc.
They don't think for themselves because in their world, someone else is making the decisions and they are okay with the results, no matter if it was bad or good.
If Joe Biden says the border is closed...in their minds, the border is closed. If Adam Schiff says Trump was involved in Russian collusion...in their minds, he was involved.
I would say the best Democrats are the ones that have passed on to the pearly gates, but then again, didn't some of them still manage to vote in the last election?

The biggest lies are about the consequences of their decisions

Now do Trumpaholics.

and add in the factors that:

1) Trump never lies; and
2) this country should be a Theocracy.

Their desire to wreck the country they’ve never hidden from anyone

Yes. They said they want to end fossil fuels and take away your guns.
