Sarah Palin makes a campaign appearance today with GOP presidential running mate John McCain in the swing state of Missouri. Here are three questions Palin could answer that might give Americans a better insight on this mystery politician:

1. Why did you get pregnant at age 43, already serving as governor of Alaska, with your oldest child already getting ready to head out the door?

It's not a disqualifer as vice president, of course, but does make me wonder about your judgment.

2. Why do you keep repeating the untruth that you told Congress "thanks, but no thanks on that Bridge to Nowhere"?

Sure, politicians mislead people all the time. But you might want to be a little different as you introduce yourself to the American people.

3. Do you really embrace McCain's policies on energy, foreign policy and the economy?

You didn't really say much of substance about those last two issues in your acceptance speech last week. And on energy, you want to drill anywhere and everywhere, where McCain has the common sense to not want to do it in your home state.
