Unfortunately he can't run. . .and even if he is a natural born citizen, he may not feel it's worth it because of how Trump was treated. It's one thing to trash talk the Swamp from a distance. . .it's another to be neck deep in it as president or a legislator.
I know he can't run...but he does deserve credit for speaking up, and for not taking the president's spin, lashing out, and blacklisting of him. And believe me I know all about the backlash you get for speaking up. So I can only cheer him on!
