WASHINGTON AP – The Supreme Court appears poised to wipe away limits on campaign spending by corporations and labor unions in time for next year’s congressional elections in a case that began as a dispute over a movie about Hillary Rodham Clinton.

The justices return to the bench Wednesday – nearly a month early – to consider whether to overrule two earlier decisions that restrict how and when corporations and unions can take part in federal campaigns. Laws that impose similar limits in 24 states also are threatened.
