voting

elastic state

A state whose voting outcome in a presidential election is relatively sensitive or responsive to changes in political conditions, such as a change in the national economic mood.

Nate Silver: “Elastic states are those which have a lot of swing voters — that is, voters who could plausibly vote for either party’s candidate. A swing voter is very likely to be an independent voter, since registered Republicans and registered Democrats vote with their party at least 90 percent of the time in most presidential elections. The swing voter is also likely to be devoid of other characteristics that are very strong predictors of voting behavior.”

An inelastic state, by contrast, is one which is relatively insensitive to these changes.

psephology

The scientific study and statistical analysis of elections and voting.

The term was coined in 1952 by Oxford Professor R. B. McCallum and is derived from the Greek word psephos, which means pebble, and references the pebbles used by the Ancient Greeks to cast their votes.

fusion voting

Fusion voting allows a candidate’s name to appear on multiple parties’ ballot lines, and to combine his or her votes from those lines. It was widespread in the 19th Century, as Democrats benefited from fusion tickets with populist parties, but now remains legal in only eight states. In those states, minor parties will often agree to cross-endorse a major party’s candidate in exchange for influence on the candidate’s platform.

split ticket

A split ticket is when a voter chooses candidates from different political parties in the same election.

straight ticket

Voting a straight ticket is when a voter chooses all of the candidates of the same party.

To facilitate straight ticket voting, some jurisdictions may allow voters to pull a lever or check a single box to choose all the candidates of a particular party.
