It’s Monday after a stormy weekend on the political scene as well. Donald Trump’s rally in Chicago on Friday night was cancelled after many protesters entered the arena where he was to speak, and as a result scuffles broke out. (No serious injuries, though). But Mr Trump did not denounce any of this .. in fact, he says he thinks it good for his campaign. And then in a new low of political opportunism (can it be anything else?), Ben Carson endorsed Trump this morning. Anyway : Super Tuesday No 3 is here tomorrow, with make-or-break primary elections for Messrs. Rubio and Kasich in their home states. If they don’t win there, they may very well have to pack it in and call it quits.
