It's better than Plurality in this regard, but not perfect.

For example:

2: Bush>Perot>Clinton  (approval vote = Bush)
1: Perot>Bush>Clinton  (approval vote = Bush + Perot)
2: Clinton>Perot>Bush  (approval vote = Clinton)

The approval vote totals are:

Bush: 3
Clinton: 2
Perot: 1

and so Bush wins. But Perot is the Condorcet winner!

The result above might make sense if the above vote reflects voter utilities similar to:


. 100 . . voter utility or rating . . 0
----------------------------------------
2 Bush . . . . . . . . . Perot . Clinton
1 Perot . Bush . . . . . . . . . Clinton
2 Clinton . . . . . . . . . Perot . Bush

But not if:

. 100 . . voter utility or rating . . 0
----------------------------------------
2 Bush . Perot . . . . . . . . . Clinton
1 Perot . . . . . . . . . Bush . Clinton
2 Clinton . Perot . . . . . . . . . Bush

I'm aware of the problems with interpersonal comparison of utilities, but have a hard time viewing the two cases as equivalent.
