Both are extremely qualified and bring with them what Trump seems to be lacking: experience leading and managing large governmental organizations and layering a staff of underlings that will support the common cause and not take their positions as self serving political opportunities. There's a difference between getting things done and just talking about getting things done. Actions always speak louder than words. Both Cruz and Desantis have trails of accomplishments without casualties.
I have praise for Trump's economic policies and for his war against our MSM in their effort to run America. I believe Trump's great contribution at this point would be to continue his battle against the MSM and stand back so more qualified leaders can step to the front of the Republican parade.
