No matter how the San Diego Rich Girl wants to spin it, the rent-a-mob failed. They failed to research the venue. They failed to scout out the locale (it's right by US 101 freeway, how hard is that!). They failed in their purpose of preventing Trump from speaking. And the Trump-Haters are an ongoing failure, because their violence is creating sympathy for Trump, and a wedge Trump could drive between The CHILL or The Bern and some of their more vociferous supporters.
And even if Trump had to enter through the kitchen, it's a fail for the Trump-Haters, because he had a chance to greet the kitchen staff!
