Sen. Thad Cochran of Mississippi has edged out Tea Party challenger Chris McDaniel in an extremely tight run-off election, according to the AP, which gives the six-term GOP veteran 51% to McDaniel's 49% with 99% of precincts reporting. The heated three-week race saw Cochran take the unusual step of reaching out to black Democrats, a move that his opponent called a desperate attempt to chase "ultraliberal" votes, the New York Times reports. Sources tell the Hill that McDaniel plans a legal challenge to the result, focusing on heavily African-American Hinds County, where Cochran received thousands more votes in the run-off than in the first round of primary voting. In another closely watched race, Democratic Rep. Charles Rangel is leading his challenger Adriano Espaillat in New York’s 13th District, Politico reports. Espaillat—who gave the 84-year-old Rangel the toughest challenge of his political career—says the race is still too close to call and has refused to concede, although the latest figures put Rangel four points ahead with 99% of precincts counted.
