It looks like Republicans have learned a new trick in the media. If you give exclusive stories to journalists with the condition that no Democrats are to be allowed to comment on the story, journalists think that's a perfectly acceptable thing to do. Not only that, but they won't even bother to do any additional research for the story.
We recently had the Washington Post doing this, with the journalists not "allowed" to contact anyone else about the story until after it would be too late for the morning paper. And now we have Roll Call doing the same.
