Rep. Dennis Kucinich, who won a national following among liberals in two colorful but unsuccessful runs for president, was defeated by fellow Ohio Democratic Rep. Marcy Kaptur, leaving his political future in question.Mr. Kucinich has visited Washington State, prompting speculation that he might run for Congress from there, and his campaign has declined to rule out that option. It would be a highly unusual move, but Washington leans Democratic and there is an open congressional seat in a Seattle-area district.
