Y'all need to pay attention to what's happening in Europe. They're not messing around. The Epstein scandal is causing heads to roll.
In America, eh, not so much. I wonder why.

This is likely a case of brood parasitism. Let's talk about it.

But on Sunday afternoon, his wife told MPR News that he still hadn't received the life-saving medication.

Donald Trump won this district in Louisiana by 13 points in 2024.
The Democrat just crushed a Republican extremist in this district by 24 points.
Folks, that’s a 37 point swing to the left. We can compete everywhere and win anywhere. Let’s keep this up!

If you are upset about the WP layoffs and the billionaire takeover of the press, consider cancelling your Amazon Prime membership and stop giving them so much business. It took us a while to adjust from the convenience of it when we quit but it was worth it.
Former Washington Post journalists have launched a GoFundMe to help repatriate fired staff members who are effectively stranded in foreign countries.
One of the richest men in the world fired them from the paper and didn’t even pay to ensure they got home.
Abolish the billionaire class:
