In cities from Boston to Los Angeles, the demonstrators chanted anti-Donald Trump slogans, with many yelling "not my president, not today", media reported. As many as 5,000 people were at a protest in New York, the police estimated. Among the issues were immigration and Obamacare. "I came out here to let go of a lot of fear that was sparked as soon as I saw the results," protester Nick Powers said. He said he feared the real-estate mogul will support stronger stop-and-frisk policies that would put many people in prison. He was worried that Trump's victory would embolden sexist views. Many of the protests were in cities with large Democratic bases -- Atlanta, Austin, Boston, Chicago, Denver, Philadelphia, Portland, San Francisco, Seattle and Washington, media noted.
