from The Conservative Treehouse:

When it comes to the private corporations in American politics known as the Republican National Committee (RNC) and the Democrat National Committee (DNC), there is a common misconception that the corporations represent the voters, they do not.

The RNC and DNC corporations represent their interests, which are not necessarily in alignment with the interests of the unpaid voluntary participants, the voters.  As a consequence, when a lawyer is hired by the RNC they are not representing the candidate or voter, they are representing the interests of the corporation. A big difference.
