Paul Davis Ryan, 1972–, U.S. politician, b. Janesville, Wis., grad. Miami Univ. (B.S. 1992). A politically active, conservative Republican, he was influenced by the economic theories of Hayek and Friedman and the political philosophy of Ayn Rand. In 1998 he first won election as a U.S. representative from Wisconsin. A member of the House Budget Committee, he became its ranking Republican in 2007 and chairman in 2011. Ryan has advocated reducing government spending, privatizing Social Security, replacing Medicare with a voucher program, turning Medicaid into block grants to states, repealing President Obama's health-care legislation, and lowering income-tax rates.

Learn more about citation styles

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
