President Andrew Johnson isn't remembered well these days...

and there are legit reasons for that, let us be honest. The man was a "piece of work" on racial issues to be sure. But let us also recall that when his home state of Tennessee seceded from the Union in 1861, Johnson loudly denounced all secession & rebellion, he chose His Country over His State.  He was the only southern US Senator to choose the Federal Union over the Confederacy, the only one.
Robert E. Lee, faced with the exact same choice, bound by oath to the US Constitution, begged by Abe Lincoln to command his armies and put down the rebellion, made the opposite decision.
Robert E. Lee chose "State before Country", and yet somehow today we are finally getting to debating what is to be done with all these statues of the Commander of the Army of Northern Virginia.  Frankly if all those statues of Marse Robert were melted down to make bronze commodes in Public Housing Projects, no one would be happier than I.  Remember that when the debate starts about the statue of Andrew Johnson in the State Capitol in Nashville Tennessee, as bad and misguided as Johnson was, he choice the Union and the US Constitution, that matters.
