I can confirm I'm a two-time Johnson-to-Biden voter myself.
However, I know one irl who stubbornly stuck with Jo Jorgensen despite half his other FB posts being total rage against Trump. Not a swing state resident though so didn't matter.
There are also plenty of self-styled "libertarians" on ImgFlip and I'm sure all over the internet who went the Trump path.
Regardless of how they broke, most felt the same way that this was an election not to "waste" a vote on.
