Probability puzzle

This puzzle came across RGP recently, and has provided some amusement around my office:

Shuffle a deck of cards. Take a card off the top, one at a time, until an ace appears.

Is the next card more likely to be the ace of spades, or two of clubs?

(consider the probability before the first card is turned, not after seeing the first ace)
