It is well past time for somebody (Hillary? Edwards?) to ask Obama a couple of important questions:
1. Are you a Democrat or an Independent?
2. If you are a Democrat, what does that mean to you? What political beliefs do you have that distinguish you from being a Republican?
3. If you are an Independent, why should Democratic voters vote for you?
4. You say that it is time to end the divisiveness of the past 20 years. What, precisely, do you mean by this? What are the divisions you plan to overcome? And how do you plan to overcome them? For example, how do you plan to bridge the divide between Republicans who insist on Supreme Court justices who will override Roe v. Wade and Democrats who want the reverse? Or those who believe that tax cuts are the solution to every domestic problem vs. those who believe that the people, especially the rich, should be willing to pay for the government services they want? Between those who believe the war in Iraq is wrong and those who believe it is right? Are you just going to wave a wand and make all happiness and light? [oops, forget that one. "Fairy tale" allusions are racist.]
5. A rather large proportion of your vocal supporters on the Web have stated that they will vote for the Republican candidate, whoever he is, rather than vote for Hillary or John. That suggests that, at best, they are voting for you as a person rather than as somebody who supports their political beliefs. What do you say to them? And to Democrats who want a Democratic President who will represent their Democratic beliefs?
