In 1992, all three Presidential candidates were lefties: Bush, Clinton, and Perot.
In 2008, both Obama and McCain were lefties.
Presidents Hoover and Ford were lefties. Truman was ambidextrous. Reagan may have been a natural lefty but back then, children were often forced to act right handed. Bob Dole may have originally been right handed but he lost the use of his right arm in WW2 and had to learn how to do everything with this left hand.
Most importantly, my father o”h was a leftie.
Clearly, there is nothing wrong with being left-handed.
