I don't think that 1/300 million part was about the likelihood of influencing the election, but rather about what percentage of the gains go to the person (not more than the percentage that that person represents of the population, presumably).

Even if you had guaranteed ability to affect the outcome of an election, supposing you knew that by spending many hours researching the correct policy to vote for you could save each person in USA $1, it would not be worth it for you to spend the time figuring it out. Although from a social perspective it would be a worthy thing to spend time on.
