I agree with Rick Wilson's take here. We've seen the crimes of this regime and its enablers, as they try to destroy the best of America while stealing all the money they can. If there's forgiveness (a big IF), it comes AFTER accountability. www.againstallenemies.net/p/no-mercy-f...

Delighted to hear that Elon Musk believes money will be useless by 2036. I wouldn't want him to be burdened with useless stuff, so I will cheerfully accept any quantity of money that he wants to get out of his life.

Everyone should be clear about the implications of the ICE murder in Maine. ICE can kill you (yes, you!) for no reason whatsoever. Your legal status doesn't matter. Whether they are seeking you doesn't matter. Good police practices don't matter. Abolish ICE.

"No matter how often Trump posts the same whiny bilge, no matter how often he claims he is making the best deal ever, and no matter how deeply he spirals into his own narcissistic orange skull, he can’t change the facts on the ground. He lost. Iran won."

He can’t win; he won’t say he’s lost. So he dithers.

I really miss the time when I could go for weeks without thinking about the US president. This idiot has so much of the world wondering whether the resolution of his manufactured crisis du jour winds up being a horrific genocide in our names, or merely more childish posturing.

Since Trump was the sitting president during the 2020 election, doesn't every possible "foreign election interference" narrative point to his team's incompetence and/or malfeasance? How can such a story possibly justify Trump taking charge of future elections?

Ah yes, the comforting delusion that Angry Baby is, deep down, a rational person and amenable to reasoned arguments. So many people continue to put forward sensible-sounding ideas about how to deflect him from idiocy. However, evidence suggests that abject flattery is the only thing that works.

This is important, but also infuriating. Not only will ICE kill you for no reason, but the federal government will immediately lie about it. www.muellershewrote.com/p/watch-new-...
