A short list or shortlist is a list of candidates for a job, prize, award, political position, etc., that has been reduced from a longer list of candidates (sometimes via intermediate lists known as "long lists"). The length of short lists varies according to the context. A candidate on a short list might not receive the award or position.
In US politics, short list is most frequently used in two instances: first a list of prospective vice presidential nominees compiled for the benefit of a party's presidential nominee, and a list of people who might be nominated by an executive office holder to a judicial or lower executive office.
In the latter instance, the short list might be compiled by the party election committee, after conducting research and undergoing a process of elimination, selecting individuals judged fit and capable of successfully completing any processes needed for acceptance. It might additionally be used for the presidential nominations of federal and Supreme Court justices.
In the former instance, its main use refers to the context of presidential nominees, as they make their choice for the vice presidential nominee. The list is typically compiled by the presidential nominee's advisers, with an eye to the characteristics of each vice presidential nominee that might boost the combined presidential ticket to victory. Under the current U.S. presidential and vice-presidential nomination regime, the presidential nominee's selection of running mate is authoritative, and will almost never be rejected by party conventiondelegates.
As a prospective vice presidential nominee is placed onto the short list they're typically subject to thorough vetting. The scrutiny involved in the vetting process usually increases as any given person whose name is on the short list comes closer to being chosen by the presidential nominee.
The media frequently claims to obtain and announces the names of individuals they believe to be on the short list. Presidential nominees' staffs might additionally quietly disclose the name of a candidate as being on the short list, in an attempt to gauge public opinion.
Typically, the most prominent individuals on the short list are those who competed well in the early presidential primary and caucus contests, but who're judged as non-threatening by the presidential nominee (for example, John Kerry's selection of John Edwards in 2004.) There are several individuals who're perennially listed as being on the short list, such as Evan Bayh and Bill Richardson for the Democrats, and Orrin Hatch for the Republicans. Although such public disclosure might be considered an honour or mark of distinction, it can additionally harm a political career if a candidate is frequently discussed but never chosen.
For literary awards, a short list (or 'shortlist') is often made public, these are the works which will be looked at closely by judges, and from which winners will eventually be chosen. Sometimes a 'long list' is prepared beforehand, from which the later short list will be selected. This is additionally at times made public.
