Democratic presidential contender John Kerry began a campaign swing Wednesday with his choice for vice president, North Carolina Senator John Edwards.

John Kerry and his newly announced vice presidential running mate, John Edwards, made their first joint appearance outside Pittsburgh before embarking on a campaign swing through Ohio, Florida and North Carolina.

"People are desperate to believe again that tomorrow will be better than today," said Senator Edwards. "That is what John Kerry represents to the American people. He represents hope."

Senator Kerry says the Democratic ticket will make the United States stronger at home and respected overseas.

"We come to this with a deep, deep belief that American can do better and today we are embarking on a new journey together, not for us, but for our country," he said.

The Bush campaign says the Kerry-Edwards ticket is one of the most liberal in history. But a new poll suggests the Edwards pick has already given Senator Kerry a boost.
