Sunday thought: Really, truly, the end of Trump is near MAGA is cracking up, but beware

If you’re taking some satisfaction from the MAGA crackup, don’t let your guard down. It’s when Trump feels he’s in trouble that he does the biggest and craziest things to deflect attention. Some thoughts... https://robertreich.substack.com/p/sunday-thought-really-truly-the-end

Cool! Does this assume fluid resistance proportional to the speed or to the square of speed?

Minneapolis police chief warns officers: Stop unlawful force by ICE or lose your job Chief Brian O’Hara says he’ll fire city police officers if they don’t intervene when immigration agents use unlawful force.

This is great. Very few people want to go to jail, get disbarred or die for this regime. Make them fight you. They will cave.

Pollster: Trump's net approval rating among voters under the age of 30 is going into a deep, dark black hole. Look at that, -46. That is a shift on the net approval of 56 points in the wrong direction since February. We almost never see drops this big, this quickly.

The fact that four hostile drones tried to hit Zelenskyy’s plane & it’s barely a blip in the news cycle should terrify everyone. We’ve been dragged so deep into the chaos era that an attempted strike on a world leader doesn’t even break through. When this becomes normal, the world is in real danger.

I know a number of folks who worship the ground Crumb walks on, even though he produces cringeworthy material like this. A superb artist with too many terrible ideas.

Bob Crumb coming out of retirement just to say "RFK Jr. is right about vaccines and my ex-wife should've taken more advice from me" is such a fitting end to Boomer Americana and everything the "alt-comix" movement claimed to stand for

Reservations made!

Note that the Horseshoe is connected to Paris Las Vegas, across the street from the Bellagio, and kitty-corner from Caesar’s Palace. It’s a great location!

Rather than supporting Spotify (whose CEO Daniel Ek is a major booster of Helsing Al-powered weapons systems) and their “Wrapped” foolishness, I’m posting my top 5 of the year from @andrewhickey.500songs.com and his magisterial “A History of Rock and Roll in 500 Songs” podcast (500songs.com).

The boats the regime is claiming are going from Venezuela to the US would need to refuel over 20 times to get to Miami.

They are lying to us.

ATTN GOVERNMENT EMPLOYEES: The VA sent out an announcement with a link for employees to self-report their disabilities. I wouldn’t do this if I were you. They’ll likely use it to discriminate against you.

Republican Elite (last week): treason to tell military to not obey illegal orders & we would never give illegal orders

Republican Elite (yesterday): we stand by orders to kill unarmed survivors of our attacks clinging to boats

Republican Elite (today): military deserves all blame for illegal acts

Since Admiral Bradley has a duty to follow the Constitution and the Uniform Military Code of Justice, he must testify-if subpoenaed-and state who ordered the “kill” strike

By throwing him under the bus, Karoline Leavitt just gave him incentive to cut a deal for immunity so he can do exactly that

I can’t promise that this is the first time a Canadian publisher of a beloved children’s book series has publicly condemned the bloodthirsty US secretary of defense’s use of its imagery to smirkingly defend heinous war crimes. I mean who can say.

Pete Hegseth is the classic example of a weakling who's been given the power to indulge in his strong-man fantasies.

The same is true of tRUmp.
