It's a little boring to argue about best presidents and worst presidents -- the pantheon is os established that it becomes an argument around the fringes. The more interesting, entertaining and telling argument, to me, is saying who the most underrated president is. So I thought I would ask. There are two kinds of underrated presidents. The first group is the acknowledged underrated presidents, the ones that everyone seems to agree, more or less, are underrated. Most frequently in this group are James K. Polk, William McKinley and James Monroe. THe really fun group is the unacknowledged underrateds ,which is anyone else you can make an argument for. I'll argue for Benjamin Harrison. He was the first president to really look abroad as a world power, through trade treaties and expanding the navy. That's a huge step in our development on the world stage.
