Democrats sought to take the offensive on healthcare Wednesday, a day before a landmark Supreme Court decision on President Obama’s signature legislative achievement.

House Democrats said the high-court ruling would be a clear indication of whether the nation’s highest court is partisan or impartial, even as they sought to raise campaign funds off the pending decision.

“We’ll find out this week if the Supreme Court is listening to the American people and following the U.S. Constitution,” said Rep. Xavier Becerra (Calif.), vice chairman of the House Democratic Caucus, “or if it’s becoming more and more what we’ve seen in the past: a partisan body no different from the Congress.”
