Democratic presidential contenders Hillary Clinton and Barack Obama sparred last night in their final debate before next week’s key primaries in Texas, Ohio, Vermont and Rhode Island. Obama received a boost Tuesday when Democratic Senator and former presidential hopeful Christopher Dodd endorsed his campaign.

Sen. Christopher Dodd: “And I am here to express my strong support for the candidacy of Barack Obama. This is a moment of unity in our country, a time when we need to come together as a Democratic Party and to get behind a candidacy that expresses the aspirations, the hopes, the ambitions of millions and millions of Americans. And I believe that Barack Obama has shown that, demonstrated that, not only in the campaign, but also in his service to his state and to his country.”
