The poll reveals relatively little difference of opinion on the issue among Democrats (85 percent opposed to the ruling), Republicans (76 percent) and independents (81 percent).

The results suggest a strong reservoir of bipartisan support on the issue for President Obama and congressional Democrats, who are in the midst of crafting legislation aimed at limiting the impact of the high court’s decision. Likely proposals include banning participation in U.S. elections by government contractors, bank bailout recipients or companies with more than 20 percent foreign ownership.

But Senate Minority Leader Mitch McConnell (Ky.) and other Republican lawmakers have praised the ruling as a victory for free speech and have signaled their intent to oppose any legislation intended to blunt the impact of the court’s decision.
