New York City’s claim to fame as the hometown of Founding Father Alexander Hamilton got an astronomical boost when Hamilton, a musical about the orphan immigrant whose outsize intellect and ferocious energy singularly shaped the newborn United States, opened on Broadway August 6, 2015. Critical and popular response was rapturous; tickets are sold out months in advance. But remember, Big Apple, it’s nice to have “Washington on Your Side.” Hamilton’s wife Eliza relocated to the nation’s capital, residing here until her death at age 97. And those “diametric’lly opposed, foes” of Mr. Hamilton, James Madison and Thomas Jefferson, each spent eight years in D.C. as U.S. President. In fact there are so many Washington sites associated with this landmark musical that a Hamilton-themed walking tour is in order.
