He is very good in this role and I agree--he should at least get an Emmy "nod" for this portrayal.
Has "24" received any Emmys? I thought I remember Keifer being nominated one year, but maybe that was a SAG. Honestly, I don't watch the awards shows anymore, so I am a bit out of the loop.
It's won some of the minor Emmy awards like sound editing and such. It's biggest awards are the two Golden Globes for the show itself and for Kiefer.
