Donald Trump, in 2016, questioned every piety and broke every rule (he questioned NATO's worth and even mocked John McCain's POW status), leading the political and media class to repeatedly pronounce his candidacy dead. But he won: because they never grasped how much people hate their elite class and therefore also hate their pieties and rules.
That anti-establishment hatred isn't the exclusive property of of Trump. In fact, Trump has utterly squandered it: there's basically no economic populism or foreign policy heterodoxy in Trump's second term, which has created a huge opening for the left to seize that mantle.
I get that if you're ensconced in DC think tank conferences or Morning Joe studios, it's Gospel that Claire Valdez's views on unions and health care and Israel are politically fatal nationwide. They're not: no more than Trump's "transgressions" were. The most potent political force by far -- not just in US politics but in the democratic world -- is hatred of establishment politics, and that has rendered almost all of the old rules entirely obsolete.
DC Democratic politicians can't embrace this kind of anti-establishment populism -- by far their most potent weapon -- because they're enslaved to a donor class that won't allow it. But their own voters are forcing it on them. Zohran's win by itself should have demonstrated all of this, but for those who didn't see it then or didn't want to, it should be extremely clear now.
New York Democrat Socialist Congressional candidate Claire Valdez lays out her radical agenda:
“So, are we ready to free Palestine, are we ready to Abolish ICE are we ready to win Medicare for all, housing for all, and unions for all?”
