Donald Trump must be defeated at all costs this November, Bernie Sanders says. He described the reality TV personality as the “most dangerous presidential candidate in the modern history of this country. I say that, not just because of his absurd views on so many issues,” Sanders told Bill Maher’s “Real Time” show Friday, recalling how Trump is a climate change denier who plans to give tax breaks to the top 1 percent. “This guy is running his entire campaign based on bigotry,” Sanders continued. “Based on trying to divide us up, based on trying to insult Mexicans, Latinos and Muslims and women and African Americans.”
