then it is unreasonable to conclude that each person's voting power is equal.

Voting power is of course exactly equal. When Fox persuades someone to vote X over Y they are exercising power but not voting power.

Also not every democracy has only 2 candidates etc etc. Voting systems vary widely and in Europe many countries have proportional representation which means there is much more diversity of candidates (who stand a real chance of being elected) and that each vote has more weight.
