The Obamas spent more than three decades building an actual marriage, raising a family, surviving the pressures of the presidency, and continuing to speak about each other with affection, respect, and candor even when discussing difficult periods. Barack and Michelle do not need to be idealized as a perfect couple; their own public comments make clear that their marriage has required work. That is precisely why the comparison with Donald and Melania is so weak.
Trump is on his THIRD marriage, has a documented history of marital INFIDELITY, and his current marriage is publicly far more SEPARATE and less visibly collaborative. To put it nicely! Melania is becoming significantly more independent from Trump’s political life and has spent substantial periods away from Washington.
So if your best rebuttal to the Obamas is “Michelle’s hair looked bad in humidity,” that says considerably more about you than it does about Barack or Michelle.
