If you’ve been following the news media over the past two weeks, then you know the big stories inside and out: an Alaskan woman wrote a book and some elected officials are working on making new laws. Or so we’ve heard. But the effects of these stories have a reach that extends well into the media world, even tickling the Mediaite Power Grid, leading to a little bit of rearrangement. Inside, find out how Meghan McCain, Andrew Sullivan and others fared.

Last week, Jake Tapper‘s potential facial hair (and high profile interviews) made him a big gain on the Power Grid — all the way up to the #2 spot. Then, he spoke out about the government’s campaign against Fox News and he came out ahead. Plus: Erin Andrews and Ann Coulter!

In our weekly recap of movement in the Power Grid, we run down all of the big shifts and their current event causes. This week, we weigh White House Correspondent Jake Tapper‘s facial hair, Sumner Redstone‘s financial woes and People magazine’s huge photo exclusive to see how they affected our leader board.

And it’s not the movement that is interesting in and of itself, but the reasons behind it.

This week, Erin Andrews is a perfect example.
