The Boston Globe:

John McCain has officially broken the limits imposed by the presidential public financing system, according to spending reports filed last week by the campaign.

The senator from Arizona has spent $58.4 million on his Republican primary effort. Those who have committed to public financing can spend no more than $54 million on their primary bid.

McCain’s lawyers contend that the spending cap no longer applies. The senator was certified to enter the matching-funds program last year when he was starved for cash. But once he started to win, he decided to hold off. On Feb. 6, after his Super Tuesday victories, he wrote to the Federal Election Commission to announce he would withdraw. His lawyers said that gave him freedom to spend as much as he wanted.

But David Mason, chairman of the commission, wrote to McCain’s campaign last month to alert him that the commission had not yet granted that withdrawal request, and that the commission would first have to vote on the matter. One snag is that the commission has four vacancies and therefore lacks a quorum to consider the matter.

Washington Post:

Knowingly violating the spending limit is a criminal offense that could put McCain at risk of stiff fines and up to five years in prison
