Daily Kos Decision-Makers?

I'm curious why the Daily Kos decided not to let its contributors blog about the John Edwards' affair, but have allowed them to blog about this story about Sarah Palin's son potentially really being her grandson. How do they decide which 'tabloid rumors' can be discussed on their site?

For true political junkies...

Check out kos' update on the electoral race. Fascinating stuff!

For this edition, the tally is Obama 336, McCain 202.
