The Republican National Committee can't think of even one:

Kagan quoted from a speech Marshall gave in 1987 in which he said the Constitution as originally conceived and drafted was “defective.” She quoted him as saying the Supreme Court’s mission was to “show a special solicitude for the despised and the disadvantaged.”

“Does Kagan Still View Constitution ‘As Originally Drafted And Conceived’ As ‘Defective’?” the RNC asked in its research document.

Can you think of one?

UPDATE: Apparently Supreme Court nominees have to pass a driver's test these days. Which means I'll never sit on the highest court in the land. Dang.
