The election is already over. Clinton has won. The EC vote is 352 for Clinton, 186 for Trump.

If this prediction is exactly correct, I will donate £50 (slightly more than $60) to the charity of your choice; if no charity is nominated within 48 hours, or the charity nominated strikes me as actively evil, I will donate to a cause supported by the Clinton Foundation of my choice.
If this prediction is not exactly correct, but Clinton still wins Arizona, Ohio, and Florida, then I will donate £20 ($24) to the charity of your choice (with the same caveats).
If neither of the above are fulfilled but Clinton wins Arizona without Iowa, I will donate £5 ($6) to Give Directly, the only charity would could do anything with such a paltry sum.
I will stick to these pledges regardless of whether you make a reciprocal one. I encourage you to do so if you are as confident as you say.
