Heinz Kerry, who married the nominee-to-be in 1995, said, "For him, the names of too many friends inscribed in the cold stone of the Vietnam Memorial testify to the awful toll exacted by leaders who mistake stubbornness for strength.

Heinz Kerry made the biggest speech of her life at a time when she is feeling the renewed glare of the campaign spotlight, after telling a Pennsylvania reporter to "shove it" during a delegation party Sunday.

"They sense, deep in their bones, that with just a change in priorities we can make sure that every child in America has a decent shot at life and that the doors of opportunity remain open to all," said Obama.
A first-generation American who grew up in Mozambique, Heinz Kerry spoke of her personal journey, which brought her to university in apartheid South African and — ultimately — into the heart of one of the United States' wealthiest families.
"I have a very personal feeling about how special America is, and I know how precious freedom is," said Heinz Kerry, who joined anti-apartheid marches. "It is a sacred gift, sanctified by those who have lived it and those who have died defending it."

The candidate, meanwhile, campaigned in Virginia and Pennsylvania en route to his arrival in the convention city on Wednesday. "I will and I can fight a more effective war on terror than George Bush is," Kerry said at a Philadelphia rally.
