Law enforcement at an anti-Trump protest in downtown L.A. after the 2016 election.Enemy territory isn't&nbsp;quite&nbsp;the right way to describe what&nbsp;President Trump&nbsp;will encounter when he arrives in California on Tuesday morning. In some parts of the region, it's not far off.The president is coming to California&nbsp;for the first time since the 2016 campaign, when each appearance in the state drew protests and in some cases violence. The visit also comes when his administration is locked in a nasty battle over immigration policy&nbsp;that has reached a fever pitch.What remains unclear is whether his brief visit will prompt major protests. Some anti-Trump activists said they intend some kind of action, but so far there have been no plans for a massive demonstration. Still, Los Angeles police and sheriff's officials are ready for spontaneous protests.Repeatedly throughout the campaign, Californians clashed with each other and law enforcement when Trump came to the state.The California Republican Party&rsquo;s convention in the Bay Area&nbsp;was a fracas from beginning to end. In Anaheim he chanted, &ldquo;Build that wall!&rdquo; as things got violent outside.After Trump was elected, thousands took to the streets in Los Angeles to send the message: Trump is &ldquo;not my president.&rdquo; More recent demonstrations as part of the women&rsquo;s march were peaceful, but&nbsp;tempers flared over&nbsp;Trump.We&rsquo;ll be using this space to cover&nbsp;the visit, from his border&nbsp;stop in San Diego to the high-dollar fundraiser in the Beverly Hills area.
