"the savings would total approximately $42 million every two years..Although savings might be limited by the need to administer county-based judicial and district attorney elections in odd-years, such elections cost significantly less than those for municipal offices" 1/2

So it would require state law changes to get rid of odd-year elections to save anything. $42 million is $5 per person in NYC. MIT says $2 billion per year nationally for elections, but how much of this is fixed and how much much is variable?

Owning and storing the election equipment pretty much will cost the same whether it is used or not. Fulltime election staff is the same whether annually or bi-annually. Savings are the ballot printing and the temp workers - including elections judges - and I have been a judge for 4 years.

I agree with higher turnout. I'm not sure about the cost. I hope someone has studied this.
