Radical May Day protests, a fixture in Los Angeles and other cities around the world, are expected to target Republican presidential frontrunner Donald Trump ahead of the California primary.

The Los Angeles Police Department has said it expects the May Day rally to be “peaceful,” according to the Los Angeles Times, but recent protests in favor of illegal immigration have been out of control. As the Times reported regarding the recent protest in Costa Mesa:

The demonstrations outside the Pacific Amphitheatre in Costa Mesa on Thursday night blocked traffic and caused tense moments. Some protesters performed screeching burnouts in their cars or did doughnuts at intersections. Others kicked at and punched approaching vehicles, shouting expletives. Ranchera and hip-hop music was blasted throughout the streets. At least 17 people were arrested, and both a Trump supporter and a teenage anti-Trump protester were hurt.

And that is just one part of the patchwork of left-wing organizations that will be showing up in the streets today, in L.A., the Bay Area, and worldwide.

Communist, socialists and anarchists appropriated the traditional spring festival on the first of May, which involves dancing, ribbons and flowers, and have turned it into their yearly focal point for nonstop cries about injustice.

This year, May Day is also the kickoff to the anticipated long, hot summer of 2016 and the road to the national political conventions to be held in Philadelphia (Democrats) and Cleveland (Republicans).

In Democrat-controlled cities across the country from New York City to Oakland, from Baltimore to Seattle, and of course Chicago – always Chicago – the shouting denizens of the American left will be out in droves to bang drums, confront the police, chant about the power of the people – and, as is increasingly the case, engage in whatever property destruction or other violence they are able to get away with.

The May Day protests will bring together, in all its glory, the coalition that still wants to fundamentally transform the United States of America. You’ll witness unions bosses, community organizers, Islamist, student radicals, teacher radicals, angry people of no specific gender, hippies, hipsters, punks, preachers and every other entitled, bitter hater with an ax to grind, letting their freak flags fly.
