We talked about Bidens health issues earlier and it was actually part of my reasoning for opening a trade on Cuomo. Not what I hope for, but from an investment point it maybe makes sense (or for me it does look valuable).
If you are a Hillary believer (are there these people ? ), there is a nice free bet opportunity between Betonline/Betfair. Betonline has @76 for Hillary next president (or winning the election to be precise) and you can lay her at @36+ at Betfair. If I max out my limit at Betonline, it would look like this:

It's a bit mixed up, because Betonline is in USD and the exchange in Euro. But you basically get your money back with the lay at the exchange and thus have a freebet on Hillary with the chance to win 10,000+ USD/EURO in the unlikely event of Hillary being the next president. You just need to have enough money at Betonline/Betfair. But it also works with smaller stakes of course.
You can also choose to make it a classic surebet. In that case you would win around 280,- Euro no matter the outcome of the election.
This is probably more an educational post, but shows what is possible.
