http://abcnews.go.com/Politics/Story?id=3165953&page=1 No Disclosure: Presidential Candidates Defy Tradition, Refuse to Release Taxes Since Watergate, Only Clinton Refused to Release Income Information EXCERPT Former Sen. John Edwards, D-N.C.,worked for a hedge fund while heading a poverty center in between his presidential campaigns. But since he isn't telling, voters can't know how much money he earned. Former Gov. Mitt Romney, R-Mass., says his wife, Ann, once donated to Planned Parenthood, but that he never contributed to an abortion-rights group himself. But there's no way for the media and the public to check that claim. Candidates Keep Taxes in the Dark In a break with the tradition of recent presidential campaigns, most of the major presidential candidates aren't releasing their income-tax filings.
