I'm in. Escrow or handshake?

Basic rules, which I hope you don't object to:

• Result is decided by the actual Electoral College meeting (not by the "pledged" counts of electors or anything like that).
• If the Electoral College doesn't meet by December 31 or some other reasonable date it's a draw (no winner).
• No presidential election in 2020 (martial law, martians invading, etc) means you lose (or a draw - not sure about this one).
• You win if Donald J Trump is elected president of the US in 2020 and I win in any other case.
• Donald J Trump not running for any reason (primaried out, dead, impeached, etc) means you lose.
• Any other candidate getting elected (democrat, republican, third party, etc) means you lose.
• If Donald J Trump is elected but doesn't get sworn in (dies, goes to prison, moves to Slovenia, etc) you win.

Anything else I'm missing?
