Actually no, the show fell victim to new writer syndrome. Commander in Chief had compelling storylines but then in the middle of the season, new writers were brought in and the show got completely hammered into death. They lost a huge chunk of the audience to that and then Idol came along to grind what was left away.
And thanks for reminding me it's the CW, Mole. Sometimes watching the network and seeing the shows becoming exactly like every show the WB had, I forget it's two networks merged. So far only Everyone hates Chris and Smackdown have avoided being WB-ized though with crap storylines and worthless nonsensical romance plots with the local dickweed just because the girls on the net find him cute.
It was the number one show on Tuesdays ...the night Idol premiered that ended...Then it went on Hiatus because of the writer situation in late January and came back on a New date and time in April and that was the eventual downfall of the show..
