CNN has the story:

John McCain and wife Cindy do not file joint tax returns, and the campaign said Friday they will not release her 2006 and 2007 tax returns along with the candidate's.

[...]

An heiress to her father's stake in Hensley & Co. of Phoenix, Cindy McCain's worth has been estimated to be around $100 million.

Thus this is what we get today from the Associated Press:

Republican presidential candidate John McCain earned a total of $405,409 last year and donated a quarter of it to charity, according to tax returns that provide only a partial picture of his family's enormous wealth.

Back in 2004, then-Republican National Committee chairman Ed Gillespie excoriated John Kerry in the media as a result of the presumptive Democratic nominee's similar decision not to publicly release information on his wife's substantial assets -- so we can assume that he will hit McCain for doing the same thing this year, right? I'm not holding my breath. (Update [2008-4-18 13:47:17 by Jonathan Singer]: In fact, Heinz Kerry did release a portion of her 2003 returns during the 2004 campaign.)

But if McCain believes that he can get through this campaign while continuing to shield from the public information on his life and his background -- the massive assets available at his disposal, his all-too-close relationships with lobbyists, his role in the Keating 5 scandal -- he is sorely mistaken. While I don't expect the establishment media, with whom McCain is overly cozy, will truly call him on these issues -- McCain effectively admitted this week that he expects the media to carry his water in order to get his message out -- do not think for a moment that McCain will not be hit over and over again, in the progressive media as well as in paid media (i.e. television advertisements, direct mail, etc.), for his clear unwillingness to be open and honest with the American people.
