Former presidents Bill Clinton and Jimmy Carter helped open the Democratic National Convention vowing John Kerry would win in November’s election.

Carter delivered the harshest critique of Bush charging that President Bush can’t run as both a war president and a peace president and he criticized Bush for waging a preemptive war.

Former Vice President Al Gore called on third party supporters to vote for Kerry. Senator Hillary Clinton introduced her husband as she called for improvements in health care and homeland security.

Tonight speakers include Kerry’s wife Teresa Heinz Kerry, former Vermont governor Howard Dean, Senator Ted Kennedy, Illinois Senate candidate Barack Obama and President Ronald Reagan’s son Ron Reagan.
