When it came time to run for office, he employed Chicago rules
to invalidate the voting petition signatures of three of his challengers.
The move denied each of them, including incumbent Alice Palmer, a longtime Chicago activist, a place on the ballot. It cleared the way for Obama to run unopposed on the Democratic ticket in a heavily Democrat district.
"That was Chicago politics," said John Kass, a veteran Chicago Tribune columnist.
"Knock out your opposition, challenge their petitions, destroy your enemy, right? It is how Barack Obama destroyed his enemies back in 1996 that conflicts with his message today. He may have gotten his start registering thousands of voters. But in that first race, he made sure voters had just one choice."
Obama's challenge was perfectly legal, said Jay Stewart of the Chicago's Better Government Association. Although records of the challenges are no longer on file for review with the election board, Stewart said Obama is not the only politician to resort to petition challenges to eliminate the competition.
