Generic ballot

A poll asking voters whether they would vote for a Democrat or a Republican for Congress without naming candidates.

Also called: generic congressional ballot, generic ballot polling

The generic ballot is a survey question that asks respondents which party they would support in their congressional district without naming particular candidates. For example, "If the election for Congress were held today, would you vote for the Republican or the Democrat?"

Analysts use the results to measure the national political environment and to forecast how many House seats each party might win. Because individual candidates' effects average out, the generic ballot is a way to gauge the standing of the parties and the president. Forecasters convert the margin to expected seats, taking account of how district lines affect the result, as gerrymandering and incumbency do, and often adjust for historical patterns, such as the president's party faring worse in a midterm election.

Its record is imperfect. The generic ballot has tended to overstate support for the party out of power in some years, and the national figure masks differences across districts and the effects of candidate quality and spending. Polls differ by whether they use registered or likely voters, and have a margin of error. Many analysts treat it as a rough guide that grows more reliable as Election Day nears.
