Someone asked me this week how the Democrats can say that President Trump presided over the worst economy in the U.S. since Herbert Hoover and how Trump can say he presided over the greatest economy in the U.S. ever. Of course, people can say anything - particularly the former president - but if they want to buttress their claims with data - there are tried and tested ways.
Someone said, "There are lies, damned lies, and statistics!" He was a politician, of course.
