[EM] Info on election method needed

[Mike Rouse]

I was looking at proportional representation methods, and found a simple 
one that probably already have a name (and probably a thorough analysis 
as well) if only I could find it.

In its simplest form, each candidate has an electoral power based on the 
number of first place votes he or she receives during the election, 
rather than transferring surplus votes to another candidate or having 
them thrown away. To give an example, if we have five candidates and 
fifteen voters, we could end up with the following

A:5
B:4
C:3
D:2
E:1

Candidates A+B, A+C, or A+D+E (for example) can pass legislation because 
they represent a majority of voters -- 9 for A+B, and 8 for the latter 
two -- while C+D+E cannot, because they represent only 6 voters. 
Theoretically, a well-beloved candidate could rule by fiat until the 
next election if he or she received 50%+1 first place votes, though this 
would probably be unlikely in any election with reasonable numbers of 
voters and candidates.

Anyway, I know there has to be some info on the properties, advantages, 
disadvantages, and strategic considerations of such a method, so any 
info or web links would be appreciated. Thanks!
