"You are just polemic".... I used to think, I was raised to think, that being polemic was a bad thing. I had to open my mind during the last 5 months and accept that a person who is almost entirely polemic, Donald Trump, can become the leader of the most powerful country on earth. Cruz and Rubio are trying hard to be like him, and they are following him rather closely in the primaries. If the American public next November votes for one of these 3 as its leader, by then, I will have TOTALLY changed my mind about the virtues of being polemic.

Or take Putin: Very polemic! But he is in the process of considerably increasing his power in the Middle East, power that he will afterwards use to influence Europe.
