In many cases, infidelity ends a marriage; in some cases, the couple works through the anger and the pain, and the marriage survives and even thrives.  Marriage is very hard work in the best of circumstances; marriages lived out in the public eye are especially challenging.  Other than the members of the couple, no one can know, with certainty, why one marriage fails and another one heals.  We do know that the Clintons saved their marriage, but rather than celebrating that fact, some of their political opponents criticize them for staying together while supporting the serial adulterer, prolific sex offender, and thrice-married president-elect.  The fact that many of these critics profess to be committed to "family values" only compounds the hypocrisy.
