National indications the enthusiasm gap among Republican and Democratic voters is narrowing seem to be reflected in Wisconsin, a state that makes for an interesting case study given Gov. Scott Walker’s deliberate strategy of confronting the “blue wave” head on. As the Washington Examiner reported last month, Walker’s re-election campaign spent much of the spring transforming his canary-in-a-coalmine routine into a “major campaign strategy” that altered everything from call scripts to fundraising emails to direct mail.

It might be working.
