It makes sense:
(1) The memos have been floating around in Kerry's campaign for what, six WEEKS?
(2) Kerry's crew likely had a good laugh over them and knew they were fakes too (note: I believe only Tom Harkin - another bumbling fool - has tried to exploit them)
(3) They just had a shake-up in the Kerry campaign -- who stood to lose power, prestige (that's a typewriter font, BTW), and position? The Old Guard: Mary Beth Cahill, Bob Shrum, Tad Devine, Stephanie Cutter.
Now find one of these who doesn't particularly like Dan Rather, and you may have your stooge.
(p.s. - CBS: why protect a bad source?? 'OUT' HIM/HER before you cease to EXIST. Are you this desparate to cling to this loser of a story?? Why???)
I think it's a no win trap. Their source is with the DNC or Kerry campaign.
Grab some popcorn, gonna be fun.
