Vermont Senator Bernie Sanders is attacking President Donald Trump for being what Sanders calls the most dangerous U.S. president ever. Sanders appeared at a rally in Denver yesterday and called Trump a racist, a sexist, a homophobe, a xenophobe and a religious bigot. Besides attacking Trump, Sanders called for radical change in America's education system as well as using a tax on Wall Street to pay off student college debt. Recent polls put Sanders in a tie with former Vice President Joe Biden among Colorado's Democratic voters.
