Take a drive down Williamson Street on Madison's east side, and you'll see a typical, placid college-town scene. The thoroughfare is lined with bars, coffee shops, tattoo parlors and houses with the standard bohemian accoutrements.
Aside from the occasional "Recall Walker" or "Solidarity" window signs, what you don't see is a lot of outward political angst in the neighborhood. Yet the people who live behind the doors that line those streets form the most powerful voting bloc in Wisconsin. And while the voters of Madison's east side may strive for a more diverse Wisconsin, their voting patterns are anything but.
For decades, Madison's quirky stock-in-trade has been its strong liberalism — yet the numbers paint a starker picture than outsiders may think. Basically, any Democrat who runs for local or state office begins with between a 7,000- and 8,000-vote lead just from wards 32, 33, 34 and 35, which run down Williamson's south side.
In 2008, Barack Obama won these four wards (PDF) with 94.7% of the vote, beating John McCain by 7,700 votes. In 2010, Dane County's own U.S. Sen. Russ Feingold pulled 95.2% (7,052 votes) against his challenger, Ron Johnson. Ironically, the Republican who fared best on the east side in 2010 was Scott Walker. He was able to muster 5.1% of the vote, as opposed to 4.8% for Johnson...end..
The rest of the article is conjecture about who might replace Tammy Baldwin, but these numbers paint an interesting picture of the "Willy Street Neighborhood".
Is there another area of the country that tilts so far left?
