I developed the campaign branding for Lloyd Princeton, running as a Libertarian for Congress in New Mexico.
The untapped disaffection that I elicited from his campaign team was that New Mexicans have a pervasive feeling that they are at the bottom of the pile among the states for most things that matter, such as education, job growth, crime etc.
I came up with the "Last No More" idea to reflect back that feeling of disaffection, exacerbated over time by the mainstream political options.
One of the particularly clever aspects of this brand is the N and M of "No More" are also the N and M of "New Mexico", which of course increases the emotional power - and memorability - of the message.
