He'd be in good company. Eugene Debs ran for president from a jail cell in 1920, having violated the Espionage Act by publicly opposing U.S. involvement in World War I. But Debs was in jail for speaking out against the war. McCain has another problem, and it isn't the unsubstantiated sex scandal. He may be in violation of his own law.

From WAPO:

By signing up for matching money, McCain agreed to adhere to strict state-by-state spending limits and an overall limit on spending of $54 million for the primary season, which lasts until the party's nominating convention in September. The general election has a separate public financing arrangement.

   ....

   If the FEC refuses McCain's request to leave the system, his campaign could be bound by a potentially debilitating spending limit until he formally accepts his party's nomination. His campaign has already spent $49 million, federal reports show. 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.

WASHINGTON (AP) -- The Supreme Court loosened political advertising restrictions aimed at corporate- and union-funded television ads Monday, weakening a key provision of a landmark campaign finance law.
The court's 5-4 ruling could become a significant factor in the upcoming presidential primaries, giving interest groups a louder and more influential voice in the closing days before those contests as well as the general election.
The decision upheld an appeals court ruling that an anti-abortion group should have been allowed to air ads during the final two months before the 2004 elections. The law unreasonably limits speech and violates the group's First Amendment rights, the court said.

''Discussion of issues cannot be suppressed simply because the issues may also be pertinent in an election,'' Chief Justice John Roberts wrote for the majority. ''Where the First Amendment is implicated, the tie goes to the speaker, not the censor.''

Yes this is a documented fact although it will be censored by RedState and others of their ilk. But they can't hide the truth forever. I can't wait until the Religious Right-Social Conservative Cabal realizes that it has to suck up to another Flip-Flopper (although not nearly as bad a Flip-Flopper as Romney) especially when it comes to abortion the one issue that turns them into frothing at the mouth rabid hysterical zealots. Fred Thompson also supported the McCain-Feingold bill which the Social Conservatives hate.  He also supported John McCain over Bush in 2000 although that shouldn't be held against anybody.

The Republican party is disintegrating right in front of our eyes especially the Religious Right-Social Conservative wing of the party. They are so desperate that the majority of them are supporting an openly pro-choice candidate (Rudy Giuliani). Social Conservatives believe that Fred Thompson will be their savior from having to support a Mormon (Romney) , a Maverick (McCain) , an openly pro-choice and pro gay rights candidate (Giuliani) or any of the other 7 candidates who don't have a chance to win.

There was a time when it was very difficult to find out where political money was coming from. There was a time when attaché cases filled with cash changed hands. These were the bad old days. You know, the days when we passed things like the Wagner Act, wage & hour laws, created the SEC, FCC, FDIC, and a whole alphabet soup of agencies. These were the bad old days when we created NASA, passed the Civil Rights Act, the Voting Rights Act, Medicare, Medicaid, and Headstart. Yes, these were the bad old days.
