I’m sure this will add a few points to Trump’s totals in California. Protests rage outside Trump rally in Orange County; 17 arrested, police car smashed.

Hundreds of demonstrators filled the street outside the Orange County amphitheater where Donald Trump held a rally Thursday night, stomping on cars, hurling rocks at motorists and forcefully declaring their opposition to the Republican presidential candidate.

Traffic came to a halt as a boisterous crowd walked in the roadway, some waving American and Mexican flags. Protesters smashed a window on at least one police cruiser, punctured the tires of a police sport utility vehicle, and at one point tried to flip a police car.

One Costa Mesa police officer was struck in the head by a rock thrown by a protestor, authorities said. The officer wasn’t injured because he was protected from by his riot helmet.

About five police cars were damaged in total, police said, adding that some will require thousands of dollars’ worth of repairs.

“Dump the Trump,” one sign read. Another protester scrawled anti-Trump messages on Costa Mesa police cars.

A very long time ago I used to live in Costa Mesa. It is the home of Congressman Dana Rohrabacher, a Libertarian Republican.
