Has anyone noticed the bias in Yahoo political "news" stories ?

It seems since the election is getting ready to ramp up that Yahoo has started their one sided news agenda again. Everything negative about Republicans, Unemployment goes over 9%, barely a word. Sarah Palin gaffs about Paul Revere, 3 days on the front page. Do to this and all the bias last election by Yahoo, I am starting an E-mail campaign to ban all Yahoo advertisers. Over the next few days I will be sending E-mails to all sponsors and letting them know of the situation. Are there any conservatives out there that agree with me ? If there are do the same and we will reach millions !
