Democratic candidates in recent years as a rule haven't felt comfortable talking about values and faith. (This may be an aversion to make "judgments" or a recognition that many, but certainly not all, segments in the Democratic coalition are relatively secularized.) The mainstream media does not have a high quotient of devoutly religious people. (It's also excessively urban and now almost entirely college-educated.) As a result, the talk of values outside the religious right has been muted in national politics.
That has changed, in part because the evangelical community has thrown values and decency overboard to support President Donald Trump, and in part because Trump's conduct, more than any recent president, shocks the conscience.
