In an all-out broadside against the current
 state of campaign finance, Sens. John McCain (R-Ariz.) and Sheldon 
Whitehouse (D-R.I.) submitted a brief on Friday morning urging the U.S. Supreme Court
 to let stand Montana's century-old ban on corporate money in political 
campaigns despite the court's Citizens United ruling two years ago 
declaring unconstitutional a similar federal law sponsored by McCain.
