The seat diagram shows only regular seats contested in this cycle, not the full Senate. Special races remain available in the state selector. Early cycles span two years and use legislative selection; missing or non-comparable vote totals are left blank. Candidate ideology is used where sourced; otherwise the broad election-era party tradition is used. Unassessed candidates are not assigned an ideology.
