According to Wikipedia, the 2005 elections in germany did cost 63 million euros, with a population of 81 million people. 0,78 eurocent per person or the 0,00000281st part of the GDP. Does not seem much, in the grander scheme of things. And since the german constitutional court prohibited the use of most types of voting machines, that figure does include the cost to the helpers; 13 million, again, not a prohibitive expenditure.
