 As Democrats, we collectively hold our breath or turn down the volume whenever we see the president, who we respect, walk off Air Force One or walk back to a mic to answer an unscripted question. Is it fair to point these things out? It has to be. This is about age, nothing more, but also nothing that can be reversed. We are not going to win in November with this president. On top of that, we won't win the House and we're going to lose the Senate.
