You don't know what the widow wanted but claim the congresswoman decided for her. How do you know that?
I concede that her performance has not been stellar but the real problem is Trump. He could have came back with a heartfelt reply that made the congresswoman look petty and rude. But oh no, Trump had to be Trump. He made the awkward statement to the widow (only he denies it others refuse to do so),and others present have confirmed it. He then threw gas on the flames with his typical bravado.
Any president gets criticized by opposition on a regular basis. Trump then has to puff out his chest and turn these criticisms into full-blown media situations.
A single or even a couple of instances don't undermine my statement about not being very good at it. It is also an opinion of mine and there is no absolute answer. Do you truly think he comes across as a caring human being?
