I put NE as both the most and least moderate, because I'm not sure how I should define "moderate". On one hand, the NE is quite moderate when functioning as an entire region and the outcome of its one-seat elections, but on the other hand, the NE's roughly equal-sized portions each have a tendency of electing some pretty polarizing representatives.
The IDS is definitely the most fiscally-conservative on balance, and the Mideast mainly wants to be tough on foreign enemies and morally pure. The Midwest is definitely more dovish and prone to mass public investment. The Pacific is drifting ever-rightward, but I don't think it stands out in any one of these categories to deserve an honorable mention.
