Williams nominated Phila. District Attorney

May 19, 2009 Williams has 40,192 votes, or about 41 percent, with 86 percent of precincts reporting. If he wins the general election, he would be Philadelphia's first black DA.

The city has for years struggled to curb gun violence and secure the cooperation of witnesses to major crimes.

Williams bested four other former assistant prosecutors, including Dan McCaffery. McCaffery had 29,585 votes, or about 30 percent.

Williams will be the favorite against uncontested Republican candidate Michael Untermeyer in November. Nearly 80 percent of the city's voters are Democrats.

Incumbent Lynne Abraham isn't running.
