Foreign Policy magazine’s Website hosts an interesting blog written by GOP foreign policy luminaries and Bush administration veterans called Shadow Government, which bills itself as featuring “notes from the loyal opposition.” It’s a good blog, filled with often-insightful critiques of President Obama’s emerging foreign policy from the right, as well as intellectually honest reconsiderations of the Bush administration. It’s also notable that an adviser to Sen. Joseph Lieberman (I-Conn.) is now contributing.

Yesterday, Vance Serchuk, a foreign policy adviser to Lieberman, wrote his first post for the blog, a thoughtful meditation about the future of the United States’ European policy. Serchuk, a former researcher for the conservative American Enterprise Institute and someone whom I’ve expressed my respect for, describes himself on Shadow Government as “in almost any imaginable respect the odd man out on this blog,” and an employee of “a Democratic member of Congress,” though you have to click through to his bio to learn that Lieberman is his boss.

He’ll be blogging in a nonofficial capacity, but it’s still a little odd that someone who works for Lieberman — who was last heard expressing support for Obama’s foreign policy team — would align himself publicly with a blog designed to provide opposition to the new administration, even if it’s loyal and constructive opposition.
