I think Karl Rove has been doing an excellent job as an analyst on Fox News Channel.
I enjoyed an interview he recently gave to GQ -- although I think my favorite part wasn't the actual interview, but enlarging the accompanying photo to see how many of the titles I recognized in his giant pile of books! It was fun to see that even "rich and famous" bibliophiles have shelving and storage issues. :)
As Power Line points out, Rove offers some interesting -- and disappointing -- insight into how Barack Obama operates.
