The Commission on Presidential Debates is a abject failure, much like Obama Care, and should be abolished. The commission own website [1]:
The Commission on Presidential Debates (CPD) was established in 1987 to ensure that debates, as a permanent part of every general election, provide the best possible information to viewers and listeners.
It seems to be a requirement of the CPD for every so-called moderator to have the politics, temperament and partisan nature of Candy Crowley. The Republican National Committee should unilaterally withdraw her support for the commission.
