This would be a strategy farce. Voters who are only interested in 
electing their favourite would all have incentive to approve, besides 
their favourite, any and all candidates
that they think that their favourite can beat in the runoff.  The net 
effect of  this strategising could be that that the two candidates in 
the runoff could be the two *least* popular
(sincerely approved).

As well of course, as Kevin pointed out, well-resourced parties  would 
have incentive to each run two candidates to try to capture both runoff 
spots.
