I would support having three regions. Combining the Midwest and Pacific and the Mideast and the South seems reasonable, but add a state or two to the Northeast
It seems reasonable if you absolutely hate competitive elections. Why combine overwhelmingly right wing regions into an overwhelmingly right wing super region (and same for the left)?
People complain that we don't have competitive elections - the only region that has somewhat competitive elections is the Northeast. The solution apparently is to combine the two non-competitive conservative regions with the two non-competitive liberal regions.
The only thing this will do is boost regional government, simply because we'll only be spread out in 3 governments instead of 5. It'll do absolutely nothing to create competitive elections.
