The answer to a question I didn’t think to ask: Why is Lincoln’s birthday not a separate holiday? Lost Cause and long memories, of course. Here’s a little look at the history of the Presidents Day holiday.
There is no US Presidents’ Day. We don’t care what the guy on red-white-and-blue stilts is saying on QVC. Some states call it that, but they can’t even agree on the apostrophe – is it President’s, or Presidents’, or Presidents? Nobody knows.
