I've been an IndyCar fan all my life (really - i went to the race in 1967 I was 4) I'm embarrassed and angered by today's event. But mostly just sad.

Trump must be impeached for undermining and subverting our free and fair elections. And when he sends ICE agents to the polls, then we must turn civic action into civil disobedience and take to the streets. Sit in. Protest. Withhold our labor. Everything must be on the table.

At this juncture I’d like to point out:
* we’re on the brink of a golden age of medical healing
* there’s enough money in the world to solve every problem in the world
* a united approach could stop the climate crisis
But a small group of sociopaths seeking personal power are going to throw it away.

The entire tech stack of energy of the 1950-2020 period has just been made almost obsolete with technology that costs under 20% in infrastructure investment cost for the same energy, and can be manufactured and installed 5x faster than the fastest fossil fuel infrastructure.
