As has been well documented on these pages, Democrats are lurching ever further left. Whether it’s their rabid and hateful opposition to President Donald Trump or their “Better Deal” socialism, Democrats are increasingly the party of extreme leftists.

The latest evidence of this seismic shift was Tuesday’s primary defeat of the number four House Democrat, Joe Crowley. On Monday, the New York Democrat who’d been in Congress since 1999 was the heir-apparent to House Minority Leader Nancy Pelosi. By Tuesday night, he was conceding a 57-42 defeat to a Millennial socialist he’d out fundraised 10-1. Alexandria Ocasio-Cortez, a 28-year-old political activist, will likely represent part of the Bronx and Queens. After all, how likely is that district to elect a Republican?

Ocasio-Cortez is a member of the Democratic Socialists of America and is backed by Bernie Sanders’ group Our Revolution. “What we need to do,” she says, “is be bold enough and courageous enough to choose leadership that takes no corporate money and advances health care, education, and housing for all.” Eliminating the federal Immigration and Customs Enforcement agency is also on her agenda. When even the leftist rag Washington Post — owned by socialist billionaire Jeff Bezos — declares her win a big loss for Democrats, that’s saying something.

Two other notable election tidbits:

First, Bradley “Chelsea” Manning lost his bid to defeat Sen. Ben Cardin in the Maryland primary. Manning’s pitiful attempt to keep his 15 minutes of fame alive came not because he’s a traitor against his country but because he’s a poster child for the transgender movement.

Second, Trump was a big winner. Soon after helping defeat South Carolina Rep. Mark Sanford with an election day tweet on June 12, Trump-backed Henry McMaster, the Palmetto State’s governor, fended off a runoff challenge from John Warren. And in Utah, Mitt Romney — yes, the same Romney who denounced Trump as a “phony” and “fraud” in 2016 — won the Senate primary with Trump’s backing. Romney will face off against Democrat Jenny Wilson for retiring Sen. Orrin Hatch’s seat in November, and that election will likely be in part about Trump. The president, Romney now says, “has exceeded my expectations.”
