Election campaign turns sour with accusations of plagiarism

DEMOCRATS in Wisconsin and Hawaii headed to the polls yesterday in a presidential campaign that has grown increasingly negative with charges of broken promises, plagiarism and petty partisanship.

Senators Barack Obama and Hillary Rodham Clinton criticised each other as they looked to break out of a tight race, fearing the prospect that neither one will secure the nomination before the convention this summer.

They entered Tuesday’s contests closely divided in the hunt for the 2,025 delegates needed for the nomination: 1,281 for Obama and 1,218 for Clinton.
