Thoughts on the ending of Godwin by Joseph O’Neill?

I just finished this book & the last couple sentences had my jaw on the floor, and I was surprised that poking around on Reddit didn't reveal another thread talking about it. I read it as the "happy" ending getting ripped from underneath you -- Lakesha looking forward to President Hillary Clinton & her life with Godwin in the same breath, when we know of course what happens with Hillary.

Are there other interpretations out there? Why would O'Neill leave us with this??
