I think this moves more of the selection process to prior to the voting. If parties don't want to offer a variety of options under their label then other candidates could be forced to stand as their own party. This might be perfectly viable for them, since you can get one of the top two slots by winning on approval. But if your hope is to get to the final two without being overall approval winner, then you need to run on a list that will get more party votes.</span></div><div dir="ltr" id="yui_3_16_0_ym19_1_1519970222161_5155"><span><br></span></div><div dir="ltr" id="yui_3_16_0_ym19_1_1519970222161_5155"><span id="yui_3_16_0_ym19_1_1519970222161_5319">The finalists are selected basically by two separate contests: One finalist is from the list containing the approval winner, and the other from the list with the most party votes. Except, that a list that satisfies both of these has to forfeit one position to the second place party list, so that we can have a second round. I understand why it works that way, and it probably makes the results better, but I think it could seem unfair.</span>. </div><div dir="ltr" id="yui_3_16_0_ym19_1_1519970222161_5155"><span><br></span></div><div dir="ltr" id="yui_3_16_0_ym19_1_1519970222161_5155"><span id="yui_3_16_0_ym19_1_1519970222161_5982">Couple of method ideas that occur to me for this setting (no party lists though):</span></div><div dir="ltr" id="yui_3_16_0_ym19_1_1519970222161_5155"><span id="yui_3_16_0_ym19_1_1519970222161_5981">1.

The single candidate with the highest approval rating (regardless of party affiliation) would be guaranteed to make it to the general election. The ballots would also be divided by party preference, such that each party's preferred candidate would be declared the party nominee.

In this particular example, the 65 voters that declared themselves either Republicans or Democrats approve of at least one candidate that advances to the general election (and additionally, another 5 Libertarians, 5 Socialist, and 5 Green also approve of one or both of the candidates, for a total of 80 voters seeing an approved candidate advance). If Ddddd had advanced instead (who had a higher overall approval), it would have been only 70 voters seeing an approved candidate advance (since 15 Republicans and 15 Libertarians didn't approve of either choice).<br><br>Turning the party choice into a jungle primary means that Democrats and Republicans aren't *guaranteed* to get the top two slots. It could mean than a Democrat and a Socialist get the top two. It could also mean that a Republican and a Libertarian get the top two.<br><br></div><div>Does this seem vaguely plausible as a system? Is there some way of gaming this system I'm not thinking of? Are there plausible scenarios where over 50% disapprove of both candidates who advance? Are there any "false flag" attacks (i.e. for a "Democrat" to declare themself "Republican" to screw up their nomination), or would the balancing act be too complicated for most voters to try?<br><br></div><div>Rob<br></div><div><div><br><br></div></div></div></div>----<br>Election-Methods mailing list - see <a href="http://electorama.com/em" target="_blank">http://electorama.com/em </a>for list info<br><br><br></div> </div> </div> </div></div></body></html>
