Sen. Russ Feingold, a Wisconsin Democrat mentioned as a possible candidate for president in 2008, announced Monday that he is getting divorced. He and his wife of 14 years, Mary, issued a statement through Feingold’s Senate office saying, “We are separating amicably and intend to remain very good friends.” The marriage was the second for both. They did not have children together. Feingold, 52, has two daughters from his first marriage. Mary Feingold has two sons from hers. Feingold has built a national following with his work on campaign finance reform, and by casting the only Senate vote against the Patriot Act. He was elected to a third term last fall. Several Web sites have sprung up urging Feingold to run for president in 2008. He has not said whether he will run.
