I don't see much to quibble with in his DCI bio, but the association with the Myanmar junta is troubling.  The correct anwer for a lobbying firm when approached by a foreign dictatorship is "No, Hell No."  The fact that they didn't see fit to say so is every bit as morally troubling to me as are Jeremiah Wright's assertions that the government might have placed AIDS deliberately.  Maybe moreso.

Stepping down from the campaign is probably the right move, but it doesn't say nice things about with whome McCain has surrounded himself. 

I can see that some businesses might be in a place to have trade relations with Myanmar.  But lobbying on behalf of a clearly corrupt, incompetent, and undemocratic government is just inches from treason.
