Six Questions CNN should, but probably won't, ask the Democratic candidates tonight

1. Does an unborn child, in any case, at any point of development, deserve protection of the law?

2. Was President Obama in error to depose Qadaffhi? Explain your calculation of the costs and the benefits of this invasion.

3. How progressive should the income tax brackets be? What should be the ratio between the marginal rate of the richest American and the poorest taxpayer?

4. Medicare and Social Security both spend more than they take in. How should this imbalance be addressed?
