I love Savannah Guthrie!
She should take over from Brian Williams, IMO. She would be the best anchor ever. If her network could hire away and back her up with Lara Logan and Trish Regan, they would have a KILLER line-up. I don't care about them being young and attractive - they are some of the best in the business. Want to get some middle-aged male news-junkies to watch your shows? Populate them with intelligent, attractive ladies. No brain-surgery, here.
