Fundraising consultants are waiting to see if the Supreme Court makes another major change to campaign finance law when it rules in McCutcheon v. FEC.

The case was heard by the court Tuesday. Despite the arguments of attorneys for Alabama businessman Shaun McCutcheon, the Republican National Committee and Senate Minority Leader Mitch McConnell, observers questioned whether the justices would be willing to reopen the issue of limitations on campaign contributions.

"There was almost nothing heard in Court on Tuesday that would suggest any such boldness," Lyle Denniston wrote on SCOTUSblog.

If the court does decide to lift the aggregate contribution limits for individuals, it could help the campaign committees increase their fundraising take but likely won't do much to help candidates who have seen their spending dwarfed by super PACs since the Citizen United vs. FEC ruling in 2010.
