Jon Green, a co-founder of Data for Progress, studied tens of thousands of newsletters sent by members of Congress since mid-2009, which were compiled by political scientist Lindsey Cormack. “Democrats are less likely to mention the Supreme Court than Republicans. And when they do mention the Court, it is more often to celebrate liberal decisions than it is to alert their subscribers when the Court has sided with conservatives,” Green said. “If this pattern is consistent across other channels of communication between the party and its voters, it could contribute to a misperception of the Court’s ideological alignment among the Democratic base.”
