Matthew Rothschild oped in the Journal Sentinel:

Special prosecutor Francis Schmitz has an obligation to appeal the decision by the state Supreme Court to dismiss the John Doe investigation. That decision legalized coordination between candidates and outside groups so long as those groups don’t say “vote for” or “vote against” a certain candidate.

Schmitz was investigating alleged coordination between Gov. Scott Walker and several outside groups during the recall elections in 2011 and 2012, but the court ordered him to close down that investigation.

Schmitz has two solid grounds for appealing that order to the U.S. Supreme Court.

The first is that the conservative justices who ruled against him, 4-2, were biased and should have recused themselves.

The second is that those justices misread U.S. Supreme Court precedents on campaign finance law and the First Amendment.
