Steve Benen:

Looking over the guest lists for all of the Sunday shows, viewers will see two Republican senators (McCain, Graham), three Republican House members (Boehner, Ryan, Schilling), three likely Republican presidential candidates (Barbour, Gingrich, Pawlenty) … and zero Democrats from Congress or the Obama administration.

It can’t be about political relevance; last I heard, Democrats held the White House and the Senate. Is it about expertise? As Benen points out, just two weeks ago McCain was warning about the menace of the Egyptian virus. And let me give some props to President Obama: I think the administration, by playing it cool but being clearly pro-democracy, has done just fine in the Egyptian affair.

So why the blackout on Democrats?
