Question:
Richard John Santorum (born May 10, 1958) is an American attorney, author, politician, and CNN Senior Political Commentator. A member of the Republican Party, he served as a United States Senator from Pennsylvania from 1995 to 2007 and was the Senate's third-ranking Republican from 2001 to 2007. He ran as a candidate for the 2012 Republican Party presidential nomination, finishing second to Mitt Romney. Santorum was elected as a United States Senator from Pennsylvania in 1994.
Santorum served in the United States Senate representing Pennsylvania from 1995 to 2007. From 2001 until 2007, he was the Senate's third-ranking Republican. He was first elected to the Senate during the 1994 Republican takeover, narrowly defeating incumbent Democrat Harris Wofford, 49% to 47%. The theme of Santorum's 1994 campaign signs was "Join the Fight!" During the race, he was considered an underdog, as his opponent was 32 years his senior. He was reelected in 2000, defeating U.S. Congressman Ron Klink by a 52-46% margin. In his reelection bid of 2006, he lost to Democrat Bob Casey, Jr. by a 59-41% margin.  After his election to the Senate in 1994, Santorum sought to "practice what [he] preached" and hired five people for his staff who were on welfare, food stamps, or other government aid.  In 1996, Santorum served as Chairman of the Republican Party Task Force on Welfare Reform, and contributed to legislation that became the Personal Responsibility and Work Opportunity Act. Santorum was an author and the floor manager of the bill. In 1996, Santorum endorsed moderate Republican Arlen Specter in his short-lived campaign for president. Reporters have observed that though Santorum and Specter differed on social policy, Specter provided him with key political staff for his successful run in 1994.  The National Taxpayers Union, a fiscal conservative organization, gave Santorum an "A-" score for his votes on fiscal issues, meaning that he was one of "the strongest supporters of responsible tax and spending policies" during his tenure, and ranked fifth in the group's rankings out of 50 senators who served at the same time.
Answer this question using a quote from the text above:

How long was he there?

Answer:
from 1995 to 2007.

input: In 1966, thanks to his friendship with Hansgen, word quickly spread to the Ford Motor Company about the young driver. Ford immediately signed Donohue to drive one of their GT-40 Mk II race cars campaigned at the 24 Hours of Le Mans by the Holman & Moody racing team. Le Mans proved frustrating for Donohue. Hansgen died while testing the GT40 in preparation for Le Mans so Donohue partnered with Australian Paul Hawkins. Donohue and Hawkins only completed twelve laps due to differential failure and finished 47th. Earlier that year, co-driving with Hansgen, Donohue finished third at the 24 Hours of Daytona and second at the 12 Hours of Sebring.  At Hansgen's funeral, Roger Penske spoke to Donohue about driving for him. In his first race for Penske, at Watkins Glen in June 1966, Donohue qualified well but crashed the car at the top of a hill, destroying it.  Donohue was invited back to Le Mans by Ford in 1967. Ford had developed a new GT, the Mark IV. Donohue co-drove in the No. 4 yellow car with sports car driver and race car builder Bruce McLaren for Shelby American Racing. The two drivers disagreed on many aspects of racing and car setup, but as a team were able to muster a fourth-place finish in the endurance classic.  In 1967, Penske contacted Donohue about driving Penske's brand new Lola T70 spyder in the United States Road Racing Championship. Donohue dominated the 1967 race, driving a Lola T70 MkIII Chevrolet for Penske. Donohue raced in seven of the eight races that year, winning six (at Las Vegas, Riverside, Bridgehampton, Watkins Glen, Pacific Raceways, and Mid-Ohio) and finishing third at the Laguna Seca Raceway round behind Lothar Motschenbacher and Mike Goth.  In 1968, Donohue and Penske returned to defend their USRRC championship with the McLaren M6A Chevrolet. Donohue did not start the first race of the year at Circuit Hermanos Rodriguez in Mexico City due to problems getting the engine to start. Despite this, Donohue still dominated the series, even though he suffered three DNFs during the season due to mechanical problems with the M6A.

Answer this question "did he win any of those races?"
output: fourth-place finish in the endurance classic.

Answer the question at the end by quoting:

Rajinikanth was born on 12 December 1950, in a Maratha family in Bangalore, Mysore State (present day Karnataka). His mother was a housewife, and his father Ramoji Rao Gaekwad, a police constable, He was named Shivaji Rao Gaekwad after Chhatrapati Shivaji, a Maratha warrior King, and was brought up speaking Marathi at home and Kannada outside. Rajinikanth's ancestors hailed from Mavadi Kadepathar, Maharashtra and Nachikuppam, Tamil Nadu. He is the youngest of four siblings in a family consisting of two elder brothers (Satyanarayana Rao and Nageshwara Rao) and a sister (Aswath Balubhai).
In 2002, Rajinikanth undertook a day-long fast to protest the Government of Karnataka's decision to not release Kaveri River water into Tamil Nadu, and announced that he would contribute Rs10 million (US$150,000) toward a plan to interlink Indian rivers. He met with Indian Prime Minister Atal Bihari Vajpayee and many experts to canvass support for the project. His hunger strike was independent of the Nadigar Sangam, who organised their own solidarity protest for the same cause. Film director Bharathi Raja lashed out against Rajinikanth, alleging that he is dividing the film industry and saying that he was a "traitor who had a tacit understanding with the Karnataka government".  In 2008, Rajinikanth took part in a hunger strike organised by the Nadigar Sangam against Karnataka's stance on the Hogenakkal Falls water dispute. In his speech, which was well received in Tamil Nadu, he warned leaders not to inflame the water project issue for political gains and requested that the issue should be resolved soon. He reprimanded politicians in Karnataka and urged them "to speak the truth" to the public. "They cannot be fooled and will not remain silent if you continue to act in such manner" he stated. The speech led to Vatal Nagaraj, leader of the Kannada nationalist group Kannada Chaluvali Vatal Paksha, demanding an apology from Rajinikanth and threatening that he and his films would be boycotted from the state of Karnataka. The threats were echoed by other pro-Kannada organisations, such as the Karnataka Rakshana Vedike. He later thanked the Kannada film industry for allowing the release of Kuselan and lifting the ban the industry had briefly imposed on it. This led to strong reactions from Nadigar Sangam members R. Sarathkumar, Sathyaraj and Radha Ravi, who called the apology a disgrace to Tamils and opined that his speech never provoked the sentiments of the Kannada people.  Rajinikanth's support toward fellow actor Ajith Kumar, who in 2010 condemned the forceful inclusion of Tamil cinema personae in political affairs, broke into a controversy.

Did he protest or anything?
His hunger strike was independent of the Nadigar Sangam, who organised their own solidarity protest for the same cause.
