Chris Rock asked that of Jesse Jackson, but it’s a question that could be asked of many of our top politicians. What do they do?

Kevin Williamson in NRO writes that Senator-surgeon Rand Paul is on “vacation” in Guatemala performing eye surgeries on poor children who need care. As the Washington Post notes, it’s not the first time Mr. Paul has done this. Dr. Paul saw two patients he first treated 15 years ago.

Kevin asks his own questions. How many politicians can you point to who can actually do something useful?

If you were a poor family in Guatemala, which would you rather have: the services of a pretty good ophthalmologist, or those of an excellent orator? (Never mind that, unlike Senator Paul, President Obama does not speak Spanish — or, indeed, any foreign language.) Imagine dispatching Hillary Rodham Clinton to Calcutta or Joe Biden to Conakry and then expecting them to do something useful. The idea is preposterous.
