Another top official to Wisconsin Governor Scott Walker during his tenure as Milwaukee County Executive has been sentenced to two years in prison for embezzling funds intended for families of veterans. The sentencing appears to close a chapter in the ongoing "John Doe" investigation into corruption and misconduct in the Walker County Executive's office, but the book remains open.

Civil rights organizations like the NAACP and groups dedicated to overturning the U.S. Supreme Court's Citizens United decision have found common ground in recent months, coming together under the "Money Out, Voters In" banner to fight the dual threats of money in politics and voter suppression. But on the other end of the political spectrum, right-wing activists like Karl Rove are drawing parallels between heroic African-American civil rights activists in 1950s Alabama and privileged 1%ers like the Koch brothers, arguing that a 1958 Supreme Court ruling protecting the NAACP's membership list should allow the super-rich to write million dollar checks without the public ever knowing.

The corrosive influence of money in politics was amplified in 2012 by the fact that in many cases we don't know which individuals or which corporations actually provided much of the funding to affect election results. "Dark money" -- election spending where we don't know the source of the funds -- played a bigger role in 2012 than in any other presidential election since Richard Nixon's.
