It’s hard to count people when a demonstration fills Market Street, from the Ferry Building all the way to Civic Center, but I think it’s safe to say more than 50,000 took the streets in San Francisco for the No Kings rally.
Similar rallies took place all over the country, with millions standing up to the Trump Administration’s policies.

From the UK Guardian:
Chicago’s mayor, Brandon Johnson, told the crowd the Trump administration had “decided that they want a rematch of the civil war”, which the white supremacist Confederacy lost to the Union in the 19th century.
“We are here to stand firm and stand committed that we will not bend, we will not bow, we will not cower, we will not submit,” Johnson said. “We do not want troops in our city.”
Rep. Nancy Pelosi was at the march.

From Mayor Daniel Lurie’s daily media schedule:
On Saturday, October 18, 2025 and Sunday, October 19, 2025 Mayor Daniel Lurie will hold internal meetings.
The mayor of Chicago is openly, aggressively, opposing Trump. The mayor of San Francisco is holding “internal meetings.”

I saw a lot of signs supporting a lot of causes, but there was definitely a trend toward blaming the billionaire class for many of the nation’s problems. Meghann Adams, a school bus driver and union leader who addressed the crowd just before the march started, talked about “where our money is going” (to the very rich) and “why we have so little.”
She said, “we can build California for the workers, not the billionaires.”
This at a time when new figures show the richest 400 Americans are with more than $6.6 trillion, and have gained $1.2 trillion in wealth in just the past year. The lowest 50 percent of the country—170 million people—has a total net worth about $4 trillion.
The level of obscenity in those figures boggles the mind.
