Rafael Edward Cruz, known as Ted Cruz (born December 22, 1970), is the former Solicitor General of the U.S. state of Texas, a position which he held from 2003 to May 2008. Cruz was appointed by Texas Attorney General Greg Abbott. He was the first Hispanic Solicitor General in Texas, the youngest Solicitor General in the United States, and had the longest tenure in the post thus far in Texas history. He is currently a partner at the law firm Morgan, Lewis & Bockius, where he leads the firm’s U.S. Supreme Court and national appellate litigation practice.

Cruz is a candidate for the 2012 Republican nomination for the United States Senate seat being vacated by Kay Bailey Hutchison.

Cruz previously served as the director of the Office of Policy Planning at the Federal Trade Commission, an Associate Deputy Attorney General at the United States Department of Justice, and as Domestic Policy Advisor to U.S. President George W. Bush on the 2000 Bush-Cheney campaign. In addition, from 2004-2009 Cruz was an Adjunct Professor of Law at the University of Texas School of Law in Austin, where he taught U.S. Supreme Court litigation.

Dennis John Kucinich ( /kuːˈsɪnɪtʃ/; born October 8, 1946) is the U.S. Representative for Ohio's 10th congressional district, serving since 1997. He was furthermore a candidate for the Democratic nomination for President of the United States in the 2004 and 2008 presidential elections.

The district includes most of western Cleveland as well as suburbs such as Parma and Lakewood. He is a member of the House Committee on Education and the Workforce.

From 1977 to 1979, Kucinich served as the 53rd mayor of Cleveland, Ohio, a tumultuous term in which he survived a recall election and was successful in a battle against selling the municipal electric utility before being defeated for reelection by George Voinovich.

Through his various governmental positions and campaigns, Kucinich has attracted attention for consistently delivering "the strongest liberal" perspective. This perspective has been shown by his actions, such as bringing articles of impeachment against President George W. Bush and Vice President Dick Cheney, and being the only Democratic candidate in the 2008 election to have voted against invading Iraq, although eventual nominee Barack Obama had also opposed the Iraq War at the time it was started, even though he had not been in Congress at the time.

He was elected to the U.S. House of Representatives in 1982, representing the Springfield-based 20th congressional district. In 1996 he won election to the U.S. Senate by an unexpected 15-point margin. He has served as Senate Democratic Whip since 2005, and assumed his current title when the Democratic Party obtained a majority in 2007.

Durbin was born in East St. Louis, Illinois to an Irish-American father, William Durbin, and a Lithuanian-born mother, Anna (née Kutkin; Lithuanian: Ona Kutkaitė). He graduated from Assumption High School in East St. Louis in 1962. During his high school years he worked at a meatpacking plant. He earned a B.S. from the School of Foreign Service at Georgetown University in 1966. He was an intern in the office of Senator Paul Douglas of Illinois during his senior year in college. Durbin earned his J.D. from Georgetown University Law Center in 1969 and was admitted to the Illinois bar later that year.
