He's brilliant, by far the smartest of the declared candidates in either party, easily in the same tier as Elizabeth Warren and Ted Cruz (not an endorsement or comparison of their positions or character, just talking raw IQ).

However, there are serious questions about how ethically he made his fortune. I haven't done a close examination, but at a glance at least one company looks like a classic pump-and-dump.

 

Excellent speaker, he can carry me along while he's talking, but when I pause the video to think about his ideas some of them fall apart.

He'll never be able to require natural-born citizens to take an exam to vote; that'll be struck down in an instant by every court in the country.

My hackles go up when he says "America is an idea." Same language as the globalist magic dirt cult.

His plan to split Russia off from China is dumb; Putin will never accept Korea-style "frozen lines of control." Trump may not have explained his plan, but I know Vivek's won't work.

 

He'd be wasted as VP and he's already said he won't accept it, but I think he'd make a fantastic chief of staff.
