The differences between winning a presidency and a Nobel Price

Sir after reading Michael Bloomberg’s “America must resist protectionism” December 12 I am torn between being happy that he is not running as a candidate and is therefore free to spell out the truths and sad because he is not running. Seems you can’t have the cake and eat it too running for president… though you can win a Nobel Prize for being environmental conscientious without even daring to spell out that gasoline/petrol taxes are needed in the US.
