Dan Balz, chief correspondent of The Washington Post, says the stakes have hugely escalated in the 2016 presidential election with the rhetoric on immigrants and Muslims entering the U.S. following terrorist attacks in France and California offered by Donald Trump. He cites experts who point out that establishment voices are being ignored as a section of the American public supports Trump's opinions. An earlier article in the Post points out that about 30% of Republicans in a PPP poll support Trump's views, and 21% unsure. Other polls show American who are older, working class and not college educated support Trump in large numbers, compared to the support from college educated and higher income people who support Sanders on the Democratic side and who oppose American intervention in the Middle East- both Trump and Sanders supporters preferring to focus on problems at home than involvement in overseas entanglements.
