Right, the answer isn't to abandon the party to these weasels.
The answer is to flood the party with people who will take it over and transform it.

Hey, a lot of people are talking about changing affiliation from Democratic to Independent.
Let me tell you why you shouldn’t do that in Colorado.
One of the main ways to get a primary challenge candidate on a ballot is to caucus for your party. You need to be registered as a Dem to caucus.

I’ve come to believe that we need to gather considerable forces and a campaign to demand the removal of face masks by ICE, Border Patrol, FBI and police.
It is a practice in conflict with the principles of transparency & accountability that are central to the concept of democracy.
