The voters who voted Terra over Dante must like Terra quite a bit, right?

Yeah, there's some potentially tricky conditional probabilities here.

If Terra only got 9% (30%*30%), that would suggest that Terra has relied entirely on dislike (anti-votes) towards Dante and Ryu rather than Terra having any fans

Somewhat. If Terra has an overall cap of .34, then someone would have to innately like both Dante/Ryu something less than .34 for Terra to even have a chance at the vote. In reality, a Terra voter may have her strength very high in his own hierarchy; but for modeling a population I think this assumption may be viable.

But... think about this: let's say Link is at strength 1.0, and he faces a million opponents at a strength of .5 (just pretending). Using that line of thinking, Link -will- get at least 50% of the vote, since he'll always wins with a random number of .5 or higher.

Hmmm....this is an excellent catch! That's a huge flaw, and a strong point in favor of King Morgoth's model.
