In NC nobody other than Biden formally petitioned to be added to the ballot. Which requires getting 10,000 signatures to show support. If Dean, Marianne, & Jill Stein would stop complaining on Twitter about not being automatically added to the ballot & actually do the legwork they could make the deadlines.
"I'm going to win president, but can't even get 10k signatures to be on the ballot" is not the flex you think it is.
