Dan Rodricks: The Maryland congressman who voted to keep slavery and committed treason

I finally settled a long curiosity about American history: Did any member of Congress from Maryland vote against the 13th Amendment to the Constitution? The 13th Amendment abolished slavery in 1865, in the final months of the Civil War. I’ve wondered about this for a while, but more recent history — the 2020 presidential election and the loser’s bogus claims that it was stolen, insurrection against the national government, regressive rulings of the Supreme Court, Donald Trump’s indictments, the Orioles climb to first place in the American League East — created distractions.
