In this post on the estate tax, I cited Drew Westen's The Political Brain as a source that Abraham Lincoln established the estate tax. I'll have to recheck the book when I get a chance to see where my confusion came from, but the current estate tax wasn't established until 1916. There was an estate tax during the Civil War, but it was repealed in 1870. I've changed the post to reflect this. The sentence "The estate tax was established ..." now reads "An estate tax was established..."
