"Leftists" whatever that even means in the US (nothing basically) are a non-entity. However, every single policy that this ambiguous "leftist" would support is insanely popular.

• Actual anti-imperialist (cloaked in anti-war)

• Healthcare as a human right (cloaked in healthcare coverage for all- call it anything you like)

• Pro abortion (cloaked in "pro choice" and "pro women")

There's a bunch more including immigration (or at least pro-immigrant), actually pro-labor, etc.

All popular stances, all leftwing if properly articulated and executed. They can't be sold as leftwing because insane Nazi country and all that. But if she ran on them, she'd be winning about ~60-80% of the national vote. Assuming the media was arm twisted into proper coverage.

Oh, and anti-genocide of course. She could just say Israel is doing genocide and as POTUS she would oversee the systematic dismantling of Israel as a nationstate... and lose like 4 votes. Because all the Nazis are already voting for orange Nazi man. The libs don't actually care. They care as much as Maddow and Van Jones tell them to care, eg "wow look at these Hamas students!" But they do not actually care about Israel. All it takes is a media narrative shift which the sitting VP/potential future POTUS can absolutely 100% force. Trump does it all the time. They have to cover what she says. She has access to the bully pulpit, although smaller ATM. She chooses right wing though. And it's actually losing her the election.

If you assume both candidates wish to win, and you must assume this otherwise the other path is pure conspiracy theory that doesn't benefit anyone, this is the better analysis. She and the democrats, her advisers specifically, are fucking incompetents. Right wing hacks. Far to the right of the general population. Which, considering America, is almost impressive...
