Note that the axes do not have the same meaning from one frame (http://voteview.uh.edu/c46105.htm) to the next; their signs are determined by the continuity of incumbents. I suppose that members of each party tend to shade marginal votes toward the average of their party; that would account for the gap. -- Anton Sherwood -- http://www.ogre.nu/
