Collin Peterson remarked last month that he is leaning to run for reelection to Minnesota’s 7th Congressional District in 2016. If he does and is victorious, he will creep even closer to the top of the list of the longest-serving U.S. Representatives in Minnesota history. The DFL congressman is only the sixth Minnesotan to win at least 13 terms to the U.S. House of the 135 elected to the chamber in state history. Peterson trails 18-term DFLer Jim Oberstar (1975-2011), 16-term Republicans Harold Knutson (1917-1949) and August Andresen (1925-1933; 1935-1958), and 14-term DFLers Martin Sabo (1979-2007) and John Blatnik (1947-1974). Andresen died in office, Sabo and Blatnik retired, and Knutson and Oberstar were defeated at the ballot box in 1948 and 2010 respectively. At 70 years, 7 months, 11 days through Monday, Peterson is currently the ninth oldest Gopher State U.S. Representative in history. DFLer Rick Nolan of the 8th CD is the seventh oldest at 71 years, 1 month, 23 days.
