In 1969, I was hoping conservative Republican John Marchi would be elected mayor of New York City, but the Big Town has too many liberals, and Republican mayor John Lindsay, whose political views were similar to those of George McGovern was re-elected. It was said at the time that Lindsay benefited from euphoria among New Yorkers after the Jets won the Super Bowl followed by the Mets winning the World Series.
My Mom hated the Yankees, so I grew up a Mets fan. I too remember when they won the World Series just a few weeks before the election, and Lindsay acted like he was on the roster, for goodness sake. “They said we couldn’t do it . . .” blah blah blah.
As a side note, you probably recall the rivalry with Baltimore, as the Jets, Mets, and Knicks (in the semi finals) beat Baltimore teams to win the championship in 1969-70 !
