Combining an approval vote with a preference vote is an example of a <br>
makeshift combination method. It cannott be justified but it is <br>
attempting to do something better, not amenable to existing methods.<br>
<br>
Approval voting is really classificatory voting. That is to say a <br>
classical logic black or white, all or nothing, approval or rejection <br>
vote. Yes, approval voting seems to be being tried as rejection or <br>
elimination voting.<br>
<br>
This corresponds to the first thing HG Wells said about that other <br>
classificatory vote, the x-vote: We no longer have elections in this <br>
country (UK) we only have Rejections. (1912. The Labour Unrest).<br>
<br>
A preference vote covers opposites and everything in between. But it is <br>
only used as an election. Preference voting can, however, also be used <br>
in an exclusion count, including the whole range of dislikes and likes. <br>
That is the system I invented.<br>
