The Wall Street Journal, 3/11/8

So, while Democrats scuffle, it’s time for Republican Sen. John McCain to start thinking about picking his running mate.

Here’s what he needs in a vice-presidential sidekick: A younger politician who is viewed as a potential president, and also can help win the South, woo social conservatives, and shore up Sen. McCain’s weaknesses on economic policy. Oh, and being a woman would be nice, too.

The person who perfectly fits that description doesn’t exist, of course, meaning this will be an interesting choice. It takes on greater importance for Sen. McCain because of the simple and unavoidable fact that he is 71 years old, and will be 72 by Election Day.
