Apparently the rules of disclosure allow them to state a range instead of exact amounts. Spousal income is also a grey area. I couldn't find the disclosures online easily. They must exist though.
I did find an article from May though -
http://www.modbee.com/2028/v-print/story/289628.htmlAnd this which puts the McCains in perspect a bit more -
http://blogs.abcnews.com/politicalpunch/2008/04/mccains-financi.htmlIn 2007, those numbers were $161,708 in Senate salary, $176,508 from book royalties, $23,157 in Social Security, and $58,358 from the Navy.
McCain gives all of his book royalty income to charity, and the campaign says that since 1991 he has "also donated the increase in his Senate salary for that year and each subsequent year to charity because he opposed the Congressional pay increase at that time and pledged not to accept the pay raises."
AND
http://cbs5.com/politics/cindy.mccain.tax.2.731600.htmlCindy McCain has released her 2006 tax returns, showing total income of more than $6 million. The wife of Republican presidential candidate John McCain paid more than $1.7 million in taxes.
McCain's campaign said she had received an extension on her 2007 tax returns and planned to make those public when they are filed.
Under a prenuptial agreement, the McCains have separate assets and file separate tax returns. John McCain made his tax returns public last month.
McCain's campaign only released the top two summary pages of Cindy McCain's 2006 return. In them, she listed itemized deductions totaling nearly $570,000. Mrs. McCain is the heiress of a large Arizona beer distributorship.
But the Clinton finances and Bill's being separate is a-okay. The McCains caught hell because they weren't going to release Cindy's returns at first.
