Wall Street Journal: “America’s two political parties have traded places economically. Where Americans once referred to upper-income ‘country club Republicans’ and blue-collar ‘lunchpail Democrats,’ they now see a working-class GOP and, in many ways, a professional-class Democratic Party.”“That is good news for Republicans, because working-class voters—often defined as those without a four-year college degree—are one of the biggest blocs in the electorate. But with that success comes a problem: The GOP now represents more constituents who rely on social safety-net programs, such as Medicaid.”
