On Tuesday, I wrote about how difficult it is to agree on the boundaries that constitute the South. (Nate Silver's "538" tackled that question today.)

The question at the heart of the debate is whether you should group the states historically (in which case the default list of southern states would be those that seceded) or whether they should be grouped using cultural/political similarities.  That set off an even broader debate -- the Fix community is nothing if not dogged in its political nerdiness -- about what the best way was to split the U.S. into regions that made actual cultural/political sense.

Maps were submitted. (Like I said, this thing escalated quickly.) I picked through them searching for a few of the most intriguing. They're below -- with credit to the the author.

Here's Aaron's proposed map.

Here's how Democratic pollster Andrew Baumann sees it.

Matthew DesOrmeaux's version.

Doug Newman's take.

Colin Woodward went with a no-states map.
