The Citizens United decision didn’t merely overturn nearly a century of federal laws and precedents; it also threw state campaign finance laws into turmoil. Before Citizens United, 24 states restricted corporate spending in elections. After the Supreme Court invalidated the federal laws governing corporate influence in political campaigns, states started scrambling to prepare for their own campaign finance laws to be struck down. And none too soon: as we’ve mentioned before, legal challenges have already started to bring down some of these state-level laws.

On Monday, Wisconsin’s attorney general formally announced that the state’s campaign finance laws would have to be repealed. A local news station reported that lifting these restrictions could lead to an increase in campaign spending from $30 million last year to $90 million this year. It remains to be seen whether Wisconson, like many of the other states affected by the Supreme Court decision, will enact disclosure laws to lessen the impact of corporate money on elections.

The conservative majority on the Roberts court didn’t just invalidate the anti-corruption measures enacted by our democratically elected Congress. It also limited the ability of state governments to decide for themselves how to regulate their own elections. Wisconsin’s election laws are just the latest casualty.
