Sampling, mark and recapture, indirect observation, and direct observation
Answer: Many of the delegates to the Constitutional Convention had serious reservations about democracy, which they believed promoted anarchy. To allay these fears, the Constitution blunted democratic tendencies that appeared to undermine the republic. Thus, to avoid giving the people too much direct power, the delegates made certain that senators were chosen by the state legislatures, not elected directly by the people (direct elections of senators came with the Seventeenth Amendment to the Constitution, ratified in 1913). As an additional safeguard, the delegates created the Electoral College, the mechanism for choosing the president. Under this plan, each state has a certain number of electors, which is its number of senators (two) plus its number of representatives in the House of Representatives. Critics, then as now, argue that this process prevents the direct election of the president.
