Democrats could have gained the majority in the House by switching less than 1/4 of one percent of the total votes -- less than one in 250 votes. [...] In contested House races in 2002, candidates typically spent $3M to $4M, although the highest was over $8M. The outcomes of the 20 closest races would have changed by swinging an average of 2,593 votes each. Assuming (conservatively) a candidate would pay $1M to switch 5,000 votes, votes are worth $200 each. [...]
In 2002, all the Congressional candidates together raised over $500M. As a result, one can conservatively conclude that affecting the balance of power in the House of Representatives is worth at least $100M to the party who would otherwise be losing. So when designing the security behind the software, one must assume an attacker with a $100M budget.
