AGE: 53
OCCUPATION: Chief Justice of the U.S. Supreme Court
NUMBER OF TIME COVERS: 1
PREVIOUS APPEARANCES ON THE TIME 100: 2
PRO: The first full term of the Roberts court saw a distinctly rightward shift, in decisions ranging from a federal anti-abortion law (upheld) to the free speech rights of high school students (cut back).
CON: Sometimes you have to wonder who's the real chief justice: Roberts or his colleague Scalia, who pushes him to move farther and faster. Also, a second seizure suffered last year means Roberts meets the criteria for epilepsy.
