“…Political scholars writing about third-party campaigns agree with Johnson’s perception that the sudden drop in third-party support toward the end of the campaign is inevitable.

Additionally, political scientists have described various cultural and structural barriers to third-party success, ranging from political socialization that creates an allegiance to the two major parties, to restrictive ballot access, single-member plurality districts, limited media coverage, and exclusion from debates (Bibby & Maisel, 2003; Gillespie, 2012; Kirch, 2015; Rosenstone, Behr, & Lazarus, 1996).…”
