Jackson had a very good record on supporting civil rights for Jews – it was the Jacksonian era when the last legal restrictions on our civil rights were removed (e.g. the famous “Jew Bill” in Maryland giving Jews political rights). Jacksonians ended property requirements for voting and extended full rights to all whites – which was a big deal back then. He was anti-Wall Street (which should appeal to both the Tea Party and the “Occupy” crowd).
Grant is probably an even better candidate to be taken off the currency. While he was very popular at the time, history sees him as excessivly incompetent as president.
Why pick on Hamilton? That’s a good question.
