JayBo has hit the nail on the head when it comes to distinguishing liberal vs. conservative (actually, Dem vs. Rep is more appropriate). All the Democrats ever do is try to demean the Republicans, without proposing their ideas. For example, all we hear is all the mistakes Pres. Bush has made in Iraq, etc. But you will NEVER EVER hear them propose what they think you be done. They rely simply on demonizing Republicans.
And even though Colmes is a dumbass for the most part, he is one of the most honest and reasonable liberals there are.
