Vice President JD Vance commands 42% support in early Republican primary polling and is "the first non-sitting president running for GOP presidential nominee to receive 50 percent or higher in New Hampshire early primary polls since at least 1980". Secretary of State Marco Rubio, at just 18¢, has reportedly said he "will do anything he can just to support the vice president" and wouldn't run against Vance. On the Democratic side, markets show fragmentation with multiple candidates clustered in low single digits - Gretchen Whitmer at 4¢ reflects the party's unsettled succession question. The early dynamics suggest Republicans have a clearer path to unity while Democrats face an open primary battle.
