I have never heard anyone use the term DINO, Democrat in name only, despite the obvious humor involved.
Is it because it’s more difficult to hide differenting views within the Democrat party? As soon as you step out of line, you’re cancelled.
I have always had my hopes up about AOC and Fetterman.
Any true DINO has left or is leaving the Democratic party. That's the difference I suppose. They don't tolerate anyone who steps out of line.
