Republicans are losing for two reasons: 1. We are the party of limited government, so we justly recoil at the idea of government forcing people to display virtuous behavior that is a function of instilled values and good character. This would not be catastrophic, except for -- 2. We have permitted government to attack and undermine the cultural institutions that instill values and good character (or reinforce them): marriage, families, our schools, our communities, our churches.
If we concede "government coercion" to the Left, AND we abdicate control over the other institutions, then we are doomed.
