PHILADELPHIA — When Katie McGinty, who’s running for U.S. Senate in Pennsylvania, took the stage, she included a section in her remarks about Donald Trump and her opponent, Sen. Pat Toomey. McGinty claimed the two men blame Mexicans, Muslims and the government for the problems in the country. It’s a strange thing to say about Toomey, who has denounced Trump’s comments in the past and has so far refused to endorse him.
