The Supreme Court did not scale back the hard-won 2002 Bipartisan Campaign Reform Act, also named the McCain-Feingold law after its sponsors, and let corporations, unions and wealthy individuals pour money into elections in time for this year's congressional races, not to mention the 2012 presidential contest; a ruling is expected as early as Tuesday, Jan. 12, 2010.
