Holding greenback and alternatives - what to do?

I see Goldman is predicting a Biden win and they are saying this will contribute to the USD falling.

I’m all cash until after the election but I’m also worried the greenback will fall on Binden election and/or unrest in the US post election. I was thinking about moving at least some cash into other currencies like Euro and CDN, but, I’m not a big FOREX follower so what’s the best currency to hold over the election or is there another suggested ways to benefit from falling USD

Is the USD falling over the remainder of '20 the current conventional wisdom or am I / GS wrong about that?
