It’s full of absolute moonbats hence the name 30 square miles of nonsense surrounded by reality. It’s the Cambridge of the Midwest
All three claims in this post are nonsense.
The people are relatively moonbats, Dane County is larger than 30 square miles, and Wisconsin is not in the Midwest. So which is the Cambridge of the Midwest: Lawrence, Lincoln, or Iowa City?
Probably a city close to the state's largest city, preferably with multiple universities, a strong leftwing lean, and a history of leftwing activism. Maybe Ann Arbor?
Madison being the state capital and also the economic engine of the state makes it quite different from Cambridge, MA.
Milwaukee is actually the economic engine of the state, Madison is the education/governmental engine of the state.
As for why it's so liberal the Republican party's platform right now is to shrink the government drastically, destroy the universities while cutting their budgets to skeletons and tell everyone who works in those industries that they're evil, un-American mongrels and it's not hard to see why they're so liberal.
Epic Systems, Exact Sciences, and Spectrum Brands would like to have a word with you about economic engines.
Milwaukee is a bunch of middling manufacturing outfits whose best days are behind them (Harley Davidson, Johnson Controls, etc).
