Lincoln's Homosexuality?

Rick Brookhiser reviews the C.A. Tripp biography of Lincoln, which, if you haven't heard, isn't quite like the Sandburg biography of Lincoln. (It's rather more like Gore Vidal's Lincoln, though more scholarly than either Sandburg or Vidal.) Brookhiser tears through a lot of Tripp's "psychology," which strikes me as rather pseudo-, but it's still hard to conclude that Lincoln didn't have erotic relationships with men.
