The 2028 Democratic vice presidential nomination remains an open contest more than two years before the convention, with trader consensus assigning the highest implied probability to Rob Sand at 22 percent amid a dispersed field where no other name exceeds 15 percent. This spread reflects the absence of a presumptive presidential nominee, leaving space for state-level officials, senators, and governors to position themselves through midterm performance, fundraising, and visibility in key battlegrounds. Factors such as regional balance, appeal to specific voter coalitions, and alignment with the eventual top-of-ticket choice continue to fragment support. Scheduled 2026 midterm results, early primary signals, and potential endorsements could narrow the field or elevate contenders with proven records in competitive districts.
