Totally agree- Juan is a better choice by far- I've seen him be fair-minded on several occasions. How did I miss Mara having a baby? I rarely miss Brit and the gang..
Mara having a baby hasn't been talked about a lot. I remember them mentioning it on the show.
Here's a snip from a blog (dated 4/30/04):
"While Wallace performs workmanlike interviews in the first half hour, the show's major problem is with the political roundtable in its second half hour, with regulars Brit Hume, Bill Kristol, Mara Liasson (now on maternity leave and replaced by Ceci Connolly of the Washington Post), and Juan Williams."
