NEW YORK -- One of the longest-serving members of Congress is in a fight just to hang on to his seat.
U.S. Rep. Charles Rangel's political fate will be decided next week in a too-close-to-call primary.
But a potential kingmaker, New York City Mayor Bill de Blasio, is remaining silent.
De Blasio managed Rangel's victorious 1994 campaign. And a poll shows that the mayor has sky-high approval ratings among black and Hispanic voters, who compose much of Rangel's district.
Yet he has chided Rangel, who is black, for invoking race in the election. Rangel's chief rival is Adriano Espaillat, a Dominican-American state senator.
The district is largely in Harlem and has long been an African-American power center. But it now contains parts of the Bronx, which is heavily Hispanic.
