Happy Presidents Day. 

Now, if you're old enough, as I am, you may remember that this day was traditionally celebrated as Lincoln's birthday.  It was transformed into President's Day in 1971, as part of the move toward more Monday holidays.

In 2005, noted presidential historian Doris Kearns Goodwin, whose best selling books included volumes about Lyndon Johnson and John F Kennedy, took on a new subject: Abraham Lincoln. 

Struck by the political acumen displayed by this simple country lawyer, Goodman titled her book 

Team of Rivals.
