Just before an election, the Secretary of State's Office releases lots of voter registration data. With an election coming up Tuesday, this season's data dump seems like a perfect excuse for a fun look at which cities are the most politically polarized.
The ground rules: To figure out the most conservative cities, we looked for the places with the lowest percentage of voters registered Democrat; for the most liberal, those with the lowest percentage of Republicans. To keep small numbers from masquerading as big trends, we excluded cities with fewer than 5,000 registered voters.
Notice that the cities where you're least likely to find a Democrat still have over 20% Democrats, but cities least likely to find a Republican are significantly lower--even less than 5%. Talk about diversity.
How's that California economy and budget coming along? Which party has run this state for the past few decades?
