The incredible shrinking McCain-Feingold act

UPI.com:
"The petition argues 'that 'independent expenditures,' which are the only currently available avenue for a political party's unlimited 'own speech,' do not adequately protect a party's First Amendment right to engage in its own core political speech. And recent judicial decisions' -- an indirect reference to Citizens United -- 'leave political parties -- traditionally favored -- at a disadvantage relative to corporations, unions, trade associations, special interest groups and political action committees ... in their ability to engage in independent expenditures.'

The petition contends the high court should hear the case so that the justices 'may answer the unresolved question and provide a test for determining when a coordinated political party expenditure constitutes the party's 'own speech,' thereby reducing somewhat the disadvantage that political parties now face.'"
