The imbalance in news coverage between Obama and McCain

The International Herald Tribune has this:

The imbalance has appeared in various analyses of the news coverage. The Tyndall Report, a news coverage monitoring service that has the broadcast networks as clients, reports that three newscasts by the traditional networks — which have a combined audience of more than 20 million people — spent 114 minutes covering Obama since June; they spent 48 minutes covering McCain. . . .

But the imbalance seems destined to get even larger:

As for the heavy coverage planned for Obama's upcoming trip, news executives said in interviews that, once again, the Democratic candidate was potentially benefiting from being a newer, untested politician. To that end, his first visit overseas since becoming the party's presumptive nominee would be an opportunity for voters to see how Obama handles one of their major concerns: his ability to handle national security matters and foreign affairs. . . .
