Interpretation
Historical Trends Interpretation
The American voter, eternally courted yet often coy, demonstrates that while turnout can rise like a phoenix and marginalized groups can reach historic polls, the persistent power of money, the quirks of the Electoral College, and the fickle nature of regional loyalties ensure the democratic process remains a thrilling, expensive, and occasionally contradictory spectacle.
