If Democrats hadn't painted themselves into an impenetrable DEI corner, they'd be able to capitalize on the H1b visa tsuris. 

They'd  pledge to eliminate the loophole that allows companies to game the system, and cheat Americans out of many tech jobs. 
They'd promise to shut down the clearing houses and visa mills and third-party slave traders and level the playing field for citizens 

But they can't.

So if the right is smart, they will pick up this crown. Maybe @JDVance is the only one clear eyed enough to do it.
