Diane Francis: Trump embraces Putin and alienates Rust Belt voters with eastern European roots

Hillary Clinton's campaign bus rattles over potholes and bumps in the US Rust Belt while Donald Trump flits around on his private jet. Such optics never seem to hurt Trump or, conversely, to help Hillary, but much depends on voters in the Rust Belt, notably in Ohio and Pennsylvania. Trump may be a master of branding but his cobranding with Russian President Vladimir Putin will damage him where he needs the most support. A voter living in Ohio or Pennsylvania doesn't have to be Ukrainian to understand that Putin and his nuclear arsenal is more dangerous to the United States than ISIS. And a significant percentage of Americans in the Rust Belt are from countries, like Ukraine, that have been victimized by Russia for generations.
