Quick note: I recently became aware of a FB page called "Libertarian Party for Justin Amash 2020".
Now, I am sympathetic to LP members who want to "Draft" Amash, even though I think he should formally switch parties and then try to hold his existing seat instead of a long shot POTUS run.
The bigger issue is that the LNC/LP National is not behind this page, and it's inappropriate for the page owners to imply that. "Libertarians for Justin Amash" would be fine, though.
I should also note the page history says at one time they were "Libertarians for Tulsi Gabbard". 🙄
