It's going to look odd in the history books.

Hillary Clinton is beginning to look more and more inevitable, if she wins it will result in this odd entry in future textbooks:

Bush
Clinton
Bush
Clinton

When schoolchildren decades even centuries from now (He typed hopefully.) open their textbooks, or scroll down them or get them injected directly into their parietal lobes they will likely find this odd column.

They will see that for the better part of thirty years, more than a generation, America, a country conceived in violent opposition to the very concept of hereditary aristocracy was run by two families.

All of this, of course, assumes that anyone is around to write any history books. Bush still has 582 days left.
