Currently, in my Kindle library, I have two books on Abe Lincoln.One is considered by scholars to be the best biography ever written about our 16th president — “Lincoln” — written by David Herbert Donald, a two-time winner of the Pulitzer.The other is a collection of the letters written by Lincoln — “Abraham Lincoln – Complete Works.”It’s his personal letters that best explore the mind of the president that most scholars rank as this country’s greatest Commander in Chief, typically followed by Washington ranked second, and FDR ranked third.Then vs. NowLincoln was actually the first Republican president elected to office,
