Voters in Southwestern Pennsylvania will choose a new Congressman on Tuesday. Their last representative, Tim Murphy, resigned after news broke that he asked his mistress to get an abortion. Voters will elect either Democrat Conor Lamb or Republican Rick Saccone. It’s a close race, but Lamb is leading in the polls. Some say Lamb’s campaign could be a good road map for Democrats who want to win back Trump-country in the midterms.
