Wonkbook: A weirdly stable campaign

This is a good moment for my typical polling disclaimer: At this point in 1980, Jimmy Carter was ahead in the polls. At this point in 1988, Michael Dukakis was ahead in the polls. At this point in 1992, George H. W. Bush was ahead in the polls. But it's not a disclaimer I fully believe.
