Full disclosure

Trust CJR's The Observer to point out something that has escaped scrutiny:

Which presidential candidate has been more forthright about their medical history?

Sen. McCain:

John McCain...released 1,173 pages of his medical records to the press. He did so only after a series of delays, however, and then granted a pool of about a dozen news outlets access to them for three hours, with no photocopying allowed.

or Sen. Obama:

Democratic presidential candidate Barack Obama released a [six paragraph] health summary from his longtime physician Thursday that pronounced the Illinois senator in "excellent health" as he struggles to quit smoking.
(via ABC)

It is fair to say there are more concerns with McCain's health, but Obama's letter is not his medical records. It's a short, undated letter from his physician.

The McCain campaign is being disingenuous when it claims to release medical records - when they in fact are merely allowing a few reporters to speed skim almost 1,200 pages in three hours.

The Obama campaign is being similarly disingenuous when it releases an undated letter that says his last "medical checkup" was in January of 2007. These are smart people - and it is no great stretch to say that there is wiggle room in there for Sen. Obama to have had some medical procedure in the last year that is not addressed by this letter.

Someone should press on this issue - and see if they squirm.
