Joe Carter has a fascinating post on what he learned during his 30 days of working for a presidential campaign.
(Fair warning: fans of Romney will not like this post.)
Quick update: For what it's worth, I don't think Joe should have mentioned the rumor (which is well known in political blogging circles). It's still a rumor.
Also, I agree with Joe about Hugh Hewitt and many of the other conservative pundits (with exceptions like Byron York). Quite sad, in my opinion.
