Didn't KO do a story on election fraud after the '04 elections?

if I remember correctly, his was the only cable news show to even touch it. Well, it's nice to see that the W. Post has finally arrived to the party, no matter how late they may be:

I'm gonna write Keith and thank him for being so ahead of the ball on this issue. Maybe these guys will even make his "Worst person in the world" list this week. Either way, if anyone is going to bring up this important issue again on the air, it will be him. With the '06 elections coming up all too soon, it;s time to start making some noise!

and covered the Conyers story, as well as Barbara Boxer voting to not accept the Ohio electoral votes. He was our hero during that time (and always is).

In fact, I would go so far as to say that Keith really began to turn me from occasional Countdown viewer into appointment-TV Countdown junkie because of his attitude toward the Ohio election situation. I was so dejected about the outcome of the election and even more depressed that it was supposedly us Ohio voters who put it over. I deeply appreciated Keith's willingness not to take the Ohio vote at face value and to question the bizarre situations surrounding the voting there.

I myself did not have a problem voting, but how do I even know whether my vote counted? I don't. That's why I use the avatar I do.

Keith is definitely a hero for being willing to pursue this story when everyone else's attitude was "Hey, it's over. Deal with it." It was not a popular stance to take, and it will never be forgotten.

you can tell from his blogs it was continuing coverage - most anything here was pretty much on air, too:

The original question was, didn't he cover this? Wasn't his the only show to do so?

Which is pretty much true.

I meant he did lots of stories, in response to the OP's question, didn't he do "a story." That's all.
