No offense meant but there are reasons why guests are chosen and why we continue seeing the ones we don't like.
For FNS, the common thread is each guest is they are their party leader of the two committees that are being talked about on FNC. I would guess the topics will revolve around current events and their committee leadership positions.
Lugar, majority chair of the Foreign Relations Committee
Warner, majority chair of the Senate Armed Services Committee
Biden, ranking minority member of the Senate Foreign Relations Committee
Levin, ranking minority member of the Armed Services Committee
No offense taken, but I was referring to FNS' dismal ratings which partly was due to the lame guests chosen & not up-to-date questioning. (what is this everyone asking the dems talking point about one-on-one discussion - many times astutely explained by the admn.) If Wallace start asking the dems why is it good now when talking one-on-one failed when Clinton ruled.
