Oh, to be young.

If there's one unifying thing that brings politicians in D.C. together, it's that most of them have been around for a long, long time. Wonkblog's Christopher Ingraham made a chart in April that shows just how long.

The same is true of the executive branch and the judicial branch. Seven of the Supreme Court justices are 60 or over.

The best part about having so many politicians with massive reserves of experience is that it becomes especially easy to find old photos of them, from days when they were idealistic and young. So idealistic and young, that they can sometimes be hard to recognize. Others, by contrast, look like they haven't aged a day.

Can you recognize some of D.C.'s longest-serving politicians from back when they first came to Washington?
