Not that this was much of a surprise to anyone in WI or follows WI politics.

In the combined counties of Waukesha, Washington, Ozaukee and Milwaukee, Gov. Scott Walker has a among Republicans and a 10% approval rating among Democrats over more than two years of in-depth polling by the Marquette Law School. President Barack Obama has a 93% approval rating among Democrats and an 8% approval rating among Republicans.

Acute partisan division has become a hallmark of American politics. But the partisan gaps in metro Milwaukee are bigger than they are in the rest of Wisconsin. They than they are in most other states. And they are massive compared to what they were in the past.
...
This geographic polarization — Democrats and Republicans clustered in different communities — is what truly separates Milwaukee from the rest of Wisconsin and many other large metros. Only one in eight voters here lived in a neighborhood decided by single digits in the last presidential contest. Almost lived in a neighborhood decided by 30 points or more.

That partisan clustering extends beyond just neighborhoods to entire counties. Metro Milwaukee isn't a patchwork of red and blue communities, like some metros. It's two giant red and blue voting blocs with a spot of purple here and there. Walker got only 36% of the vote in Milwaukee County in 2012, but won 73% of the vote in the Republican counties of Waukesha, Washington and Ozaukee. Obama got 67% of the vote in Milwaukee County in 2012 and just 32% of the vote in the rest of the area — the biggest gap between urban and suburban counties in any top 50 metro except New Orleans.
