I don't think a majority of 28% is that big a deal. When you compare it to America where there is only two major political parties, is seems small because the winner typically has a percentage of over 50%. If you added just 1 more more major political party then the amount of votes to win could be like 34%. There is also the factor of uncounted votes that people mentioned before.
I think you should be able to have your second or third votes go towards your first vote if you wish. Or better yet different governments could have different voting rules, some could have the original system, others could have where you can combine votes, and a third where there is only one vote to place.
Technically, 33% of eligible voters voted for Obama--69 million divided by 208 million eligible voters. 28% of eligible voters voted for McCain. 37% of eligible voters voted for nobody.
