Why is Obama so secretive?

Among the key documents that Obama continues to shield from the public:

Obama released just one brief document detailing his personal health. McCain, on the other hand, released what he said was his complete medical file, totaling more than 1,500 pages.

Obama refused to offer his official papers as a state legislator in Illinois. Nor did he produce correspondence, such as his schedules of appointments or letters from lobbyists, from his days in the Illinois state Senate.

Obama did not release his client list as an attorney or his billing records. He maintained that he performed only a few hours of legal work for a nonprofit organization with ties to Tony Rezko, the Chicago businessman convicted of fraud in June 2008 but did not release billing records that would prove this assertion.

Obama ignored requests for his records from Occidental College, where he studied for two years before transferring to Columbia University.

Obama’s campaign refused to give Columbia, where he earned an undergraduate degree in political science, permission to release his transcripts. Former President George W. Bush and presidential contenders Al Gore and John Kerry all released their college transcripts.

Obama did not agree to the release of his application to the Illinois State Bar, which would have cleared up intermittent allegations that his application may have been inaccurate.

Obama did not release records from his time at Harvard Law School.

During the presidential campaign, McCain’s campaign released a full list of all online donors. Obama’s campaign still has not released the names of those who donated at least one-third of the $750 million he raised.

Ironically, Obama accused the Bush White House of being "one of the most secretive administrations in our history," and chided then-Sen. Hillary Clinton for not releasing her White House schedules.
