In theory, saints have a lot more votes. But I would suspect that the percentage of votes used decreases over time. I know that the first few levels, I had so many things I wanted to vote for, I was always out of votes with a list of nodes to vote on the next day. Then, by the mid-levels, I almost always had some left by the end of the day, often 50%. Now, I'd be surprised if I use 40 votes in a year.

But does this lead to disproportionate voting power, even if I were to use my 40 votes daily? Given the restriction that I can only vote once on a given node, I think it does not. I actually think my voting power has decreased. With more people joining, the average node reputation continues to climb. My one vote means less in the grand scheme of things.
