Explanation:

Analyze the impact of Same-Day Registration (SDR) on voter turnout

Same-day registration (SDR) lowers the institutional barriers to voting by allowing eligible citizens to register and vote at the same time on Election Day. Political science research consistently demonstrates that SDR increases overall voter turnout.

Identify the demographic groups most impacted by SDR

The registration requirement is a significant barrier particularly for younger, highly mobile, and less-educated individuals who may miss traditional registration deadlines. Consequently, implementing SDR has the greatest positive impact on turnout among the young and less educated.

Evaluate the given options

• Option 1: "SDR has no effect on turnout..." — Incorrect, as empirical evidence shows a clear positive effect.
• Option 2: "SDR increases turnout, particularly among the middle-aged and affluent." — Incorrect, as these groups already have high registration and turnout rates.
• Option 3: "SDR increases turnout, particularly among the young and less educated." — Correct, as it targets the groups most constrained by registration deadlines.
• Option 4: "SDR has no effect on turnout..." — Incorrect.

Answer:

• SDR has no effect on turnout: the rich vote more often, the poor less so.
• SDR increases turnout, particularly among the middle-aged and affluent.
• SDR increases turnout, particularly among the young and less educated. (Correct answer)
• SDR has no effect on turnout: the poor vote more often, the rich less so.
