I have regularly stated that Trump spends political capital unwisely. More than anything else, that bothers me.
I would also like for him, or whoever our next president will be, to spend more energy to unite Americans. I saw very little of that from Trump. Neither party is doing that right now. We haven't had a president do that since W and that was back in 2002-03.
Before we give W too much credit, al-Quada gave him a HUGE assist in getting that done. It didn't last long, of course.
To Trump's credit, he was right in his tendency towards isolationism...whereas I was wrong. I thought he was making a mistake.
