Look at his campaign. Any problem staff early on, he addressed. He seems to have chosen well. Look at Cruz's staff from *ell. Trump also has very excellent knowledge of what people have potential to clean things up, because he's not a pol. What is there in Cruz's or Rubio's resume that would make them qualified to make good choices to fill those jobs?
You can't clean up what's inside the DC sewer with an insider. Cruz might have looked okay for awhile, but in fact he's the ultimate insider. What has he accomplished that isn't a government job and an Ivy League education?
I tend to agree with you. It’s just that it is a real question whether Trump will rely on those who aren’t Ivy Leaguers (like himself) or those with primarily government experience. Businessmen are used to relying on consensus experts.
