A few more points to mull about the Duke saga.
First, remember that "co-conspirator #1" in the charges against Duke is Brent Wilkes, a defense contractor who owns ADCS Inc.
In addition to various other bribes he gave Duke, Wilkes also rented a corporate jet which appears to have existed more or less entirely to ferry around members of Congress. Mainly Duke. But also Rep. Tom DeLay and Acting Majority Leader Roy Blunt. Wilkes is also an '04 Bush Pioneer.
Also, it's pretty stunning to see members of Congress admit to good-old-fashioned bribes. Not campaign contributions or overseas junkets, but old-tried-and-true lump sum cash payments.
But bribes are a means to an end. So pay attention to the context. This is a defense contracting scandal. Defense contracting scandals get you into the Department of Defense, particularly in a case like this in which the contracts are top-secret military spending programs over which there is little or no oversight.
