That said, I don't think you are correct, at all, when you say that money is the only thing that matters. Votes matter. For example: The Nov 2012 Los Angeles elections. I voted in those elections. Mayor Garcetti won the election with only 5.4% of the city voting for him [0]. That means that I voted for ~20 Los Angelenos with my single ballot. Basically, I voted for half my homeroom in High School. You cannot buy votes nor stuff ballot boxes at the exchange rate I was able to affect with my single vote. And this was a presidential election, where turnout is typically higher. For the majority of local elections, I was voting for nearly my entire graduating class!
Another good example was Eric Cantor's primary election in 2014 [1]. Despite being the House Majority Leader, and despite outspending his opponent not just 2 to 1, not just 10 to 1, but 40 to 1, Cantor LOST. And it wasn't close, he lost 45% to 55%, a 10 point difference. Cantor resigned as Majority Leader on July 31st.
Money does not count.
Your. Vote. Counts.
