http://www.mi-democrats.com/topics/cd_totals.pdfHere are the results by Congressional District. Kerry won all 15 districts, but in the 14th District, which is majority black and includes much of Detroit, he only beat Sharpton by about 5%. The 13th District, where Sharpton also did well, is also a majority black district that includes part of Detroit. The only other district besides these 2 in which Kerry got less than 50% was the 15th, which includes Ann Arbor and thus is probably why it was Dean's best district.
