The 10th District Democratic congressman was facing his first threat of losing the seat he has held for 12 years. Kucinich spent thousands of dollars on television ads and agreed to debate his opponents - chief rival Cleveland Councilman Joe Cimperman and three other candidates.
The 61-year-old former Cleveland mayor said he was encouraged by the results. "I am also encouraged because I know of all the hard work you have all put in," he told supporters at the North Shore AFL-CIO Federation of Labor union hall.
Cimperman hammered away at Kucinich's second long-shot presidential bid, constantly citing votes he missed in Congress while running for the White House and the financial support he received from Hollywood stars like Sean Penn.
Cimperman, 37, spent at least $500,000 trying to win the seat and gained the endorsement of Cleveland Mayor Frank Jackson.
"We took someone who ignored the district for 12 years and made him pay attention," said Cimperman, speaking from Around the Corner in Lakewood.
Cimperman, who lives outside the district, said it was too early to say whether he would consider another run for the 10th District seat. The district encompasses Cleveland's West Side and Cuyahoga County's western suburbs.
While Cimperman said he always considered the campaign a two-way race, the crowded field did not help his chances.
