Turnout will determine whether Rep. Charlie Rangel's 42-year run in the House will continue, a Democratic strategist says. Rep. Charlie Rangel faces four opponents in Tuesday's Democratic primary Pundits predicted Rangel's career over after House censure, redistricting Ethics panel found 21-term congressman guilty of tax, financial disclosure violations Challenger says President Obama's lack of endorsement of Rangel is telling (CNN) -- Rep. Charlie Rangel is fighting for the Democratic nomination in a newly redrawn New York district after a more than four-decade-long congressional career. He has been one of the most high-profile lawmakers who hit a low point in 2010 after his censure on the House floor. The 21-term representative is locked in a five-way race Tuesday for the nomination in his Harlem-area district that now has more Latino-Americans than African-Americans, a shift that has no doubt helped Rangel's fiercest competition, New York state Sen. Adriano Espaillat. But Rangel challenger and former Bill Clinton aide Clyde Williams does not see race as an issue. "I don't see it as anything that's a challenge," Williams said Tuesday morning on CNN's "Early Start." The district has been at least 46% Latino for a while under Congressman Rangel. Again I think the most important thing people want you to articulate is a real vision and an understanding of how you are going to address their problems. He became the first African-American chairman of the powerful Ways and Means Committee after Democrats won control of the House of Representatives in 2006. I'm just smarter than you," Rangel said last week, according to CNN affiliate WCBS-TV. Longtime Democratic strategist Hank Sheinkopf said Tuesday's results will hinge on turnout, especially given that New York has not held a June primary since 1973. Rangel has disputed the ethics committee's findings. "But the most important thing, if people would read the website of the Ethics Committee, read The New York Times about a month ago, where Sam Roberts put an expose out against the conduct of the committee," Rangel said Tuesday on CNN's "Starting Point." Right now, that committee is under investigation by private counsel for wrongdoing. And that's behind us. The Times reported that Rangel said he admitted to the accusations under intense pressure from party leaders. The Democrat leadership was telling him, " 'If you're going down the tubes, don't take the party with you,' " the newspaper quoted Rangel as saying. Rangel, Espaillat and Williams will face fellow Democrats Joyce Johnson, a business executive, and former Rangel intern Craig Schley to win control of the new 13th Congressional District, which stretches from East Harlem to the northwest Bronx. New York Gov. Andrew Cuomo endorsed Rangel on Friday, citing his decades of service and ability to "bring things back to the state of New York." When describing a conversation with a top figure at one of the papers, Rangel said, according to Politico, "I looked her in the eye, and I said, 'Just tell me how the editorial board of The New York Times could say that Clyde Williams would be a better representative for my district, my state and my country.' " Williams said the fact that neither Clinton nor President Barack Obama has endorsed Rangel is telling. "President Clinton came out and said he would not endorse Charlie Rangel because I was involved in this race," Williams said. President Obama has not endorsed a Democratic incumbent, which is typically the norm for a president who is sitting in office. So they have not endorsed me, but they have not endorsed him either. In the face of a changing district, fellow Democratic Rep. Luis Gutierrez of Illinois called Rangel's challenge a "tough race." "The demographics of the district, Harlem and Manhattan, are different," Gutierrez said on "Early Start." Rangel defeated Powell's son in the 2010 Democratic primary. The congressman grew up in poverty, was abandoned by his father and lived with an aunt and uncle in the Bronx. The high school dropout enlisted in the Army and was awarded the Bronze Star for valor in the Korean War after helping rescue 40 men trapped behind Chinese lines. After the war, Rangel used the GI Bill of Rights to earn a degree from New York University and a law degree from St. John's University.
