McCain released his tax returns today. They include 2006 and 2007 and nothing previously. In addition, no returns or summaries are included for wife Cindy McCain, who heads a privately held beer distribution company. Also note, John and Cindy McCain have filed separate tax returns for every year of their marriage except their first year, 27 years ago. On questions of transparency, the McCain campaign points out that the Arizona senator has filed financial disclosures while he has been in public life. The campaign cites Teresa Heinz Kerry, John Kerry's wife, as precedent for not releasing Cindy McCain's returns -- even though Heinz Kerry loaned money to her husband's campaign.
But Clinton and Obama have both released their tax returns dating back to 2000 (Clinton released a summary for 2007, but not the full return yet), and Clinton further back than that, since the days her husband was governor of Arkansas in the 1980s. Additionally, the Clinton campaign has recently called on Obama to release his tax returns from 1997 to 1999 when he was an Illinois state senator.
