I think you guys got PvK all wrong:

Here's how I think what he said is supposed to work:
1) When you vote, you can choose as many of the candidates as you like. Zero and All are both acceptable votes.
2) Any candidates with less than 50% (or number of your choice) of the votes are eliminated from any future calculations.
3) If one or more candidates remain after step 2, the one with the most votes wins.

So, For example:
4 candidates: Zack, Yolonda, Xavier, and Wanda.
8 voters: Alice, Bob, Cindy, David, Elaine, Fred, Gerald, and Helen.

Alice votes for Zack.
Bob votes for Zack and Xavier
C votes for Y,X,W
D votes for X,W
E votes for Z,Y,W
F votes for Z
G votes for Z,W
H votes for Z,W

Totals:
Zack - 6/8 = 75% approval
Yolonda - 2/8 = 25%
Xavier - 3/8 = 37.5%
Wanda - 5/8 = 62.5%

Thus, Yolonda and Xavier are kicked out of politics, and Zack gets the job.
