The Pulitzer Prize does not automatically consider all applicable works in the media, but only those that have specifically entered. (There is a $50 entry fee, paid for each desired entry category.) Entries must fit in at least one of the specific prize categories, and cannot simply gain entrance for being literary or musical. Works can also only be entered in a maximum of two categories, regardless of their properties.
Each year, 102 jurors are selected by the Pulitzer Prize Board to serve on 20 separate juries for the 21 award categories; one jury makes recommendations for both photography awards. Most juries consist of five members, except for those for Public Service, Investigative Reporting, Explanatory Reporting, Feature writing and Commentary categories, which have seven members; all book juries have three members. For each award category, a jury makes three nominations. The board selects the winner by majority vote from the nominations or bypasses the nominations and selects a different entry following a 75% majority vote. The board can also vote to issue no award. The board and journalism jurors are not paid for their work; however, the jurors in letters, music, and drama receive a $2,000 honorarium for the year, and each chair receives $2,500.
Some critics of the Pulitzer Prize have accused the organization of favoring those who support liberal causes or oppose conservative causes. Syndicated columnist L. Brent Bozell said that the Pulitzer Prize has a "liberal legacy", particularly in its prize for commentary. He pointed to a 31-year period in which only five conservatives won prizes for commentary. The claim is also supported by a statement from the 2010 Pulitzer Prize winner for commentary, Kathleen Parker: "It's only because I'm a conservative basher that I'm now recognized."
