John McCain is really going to regret daring Barack Obama to go to Iraq. All three broadcast network news anchors will be going along. They are eager to cover the candidate's rock star following in Europe and elsewhere.

I'm sure we will hear plenty of whining about bias from the McCain camp. And there certainly might be some. But the networks are going where the crowds are. Obama is a good news story for America, in a pit of bad news stories. And it's the network brass, concerned about viewership and advertising, who make these decisions to spend money sending their stars overseas to cover a story they could do from the studio.
