The post with the Free Stater plan to commit voter fraud in NH has been removed. Sadly for them, there are screengrabs so they can't pretend to deny that this ever happened.
The subreddit now has devolved into a neener neener back and forth with Free Staters and those who oppose them.
Apparently this is the GOP's latest plan. They're so desperate to prove that voter fraud is a problem in NH that they're going to commit it themselves.
