1. It is 1 in 10 million if you live in a swing state.

2. You expect $6 trillion, that figure is incorrect as mseebach2 points out.

3. The probability of winning the state lottery might be 1 in 10 million. So I'm far better off buying a lottery ticket, since in the improbable event of winning I would actually make money, in contrast to hoping that the improbable event of my vote tipping the balance and creating a stronger economy would improve my income (the contrary might be true).
