The NYC Campaign Finance Board Smacks Bill Thompson

When former NYC Comptroller Bill Thompson conceded defeat to Bill DeBlasio in the Democrat primary he said something interesting.   Besides the usual call for party unity, Thompson said that the NYC Campaign Finance board said they would not provide funds for a campaign for a runoff between the two if the Board of Elections determined it would be required. Thompson said that the board's justification was that he was unlikely to win.  Keep in mind that the CFB provides candidates with a six-to-one payout of taxpayer funds for each dollar the campaign raises.

While their evaluation of his prospects was almost certainly correct, why should the Campaign Finance Board's members or staff make judgments of the campaign's prospects?
