We wouldn't want to claim that CNN, ABC and/or NBC are closed-minded, now would we? Or that they don't allow fair and open discussion on their sites? Of course not.
Then why is it that if you vote in a poll that you believe Sarah Palin won the debate, your vote doesn't register?
And why is it that if you blog the reasons you believe Sarah beat Ol' Joe, the blog doesn't post BUT if you try blogging in favor of Obama (so, I lied), it does?
It's one thing to be "in the tank" for Obama -- it's quite another to refuse discussion. But it's obvious that to the networks free speech is for everyone who agrees with them and everyone else can sit down and shut up.
