His victory in the Iowa caucuses is widely believed to be the tipping point where Kerry revived his sagging campaign in New Hampshire and the February 3, 2004, primary states like Arizona, South Carolina and New Mexico. Kerry then went on to win landslide victories in Nevada and Wisconsin. Kerry thus won the Democratic nomination to run for President of the United States against incumbent George W. Bush. On July 6, 2004, he announced his selection of John Edwards as his running mate. Democratic strategist Bob Shrum, who was Kerry's 2004 campaign adviser, wrote an article in Time magazine claiming that after the election, Kerry had said that he wished he'd never picked Edwards, and that the two have since stopped speaking to each other. In the 2004 Democratic presidential primaries, John Kerry defeated several Democratic rivals, including Sen. John Edwards (D-North Carolina. In a subsequent appearance on ABC's This Week, Kerry refused to respond to Shrum's allegation, calling it a "ridiculous waste of time." <SEP> Days before Kerry announced Edwards as his running mate, Kerry gave a short list of three candidates: Sen John Edwards, Rep Dick Gephardt, and Gov Tom Vilsack. On July 6, John Kerry selected John Edwards as his running mate, shortly before the 2004 Democratic National Convention in Boston, held later that month. Heading into the convention, the Kerry/Edwards ticket unveiled their new slogan—a promise to make America "stronger at home and more respected in the world." Kerry made his Vietnam War experience the prominent theme of the convention. In accepting the nomination, he began his speech with, "I'm John Kerry and I'm reporting for duty." He later delivered what may have been the speech's most memorable line when he said, "the future doesn't belong to fear, it belongs to freedom", a quote that later appeared in a Kerry/Edwards television advertisement. <SEP> kerry and his second wife, mozambican-born businesswoman and philanthropist maria teresa thierstein simões ferreira (known as teresa), the widow of kerry's late pennsylvania republican senate colleague henry john heinz iii, were introduced to each other by heinz at an earth day rally in 1990. early the following year, senator heinz was killed in a plane crash near lower merion. teresa has three sons from her previous marriage to heinz, henry john heinz iv, andré thierstein heinz, and christopher drake heinz. heinz and kerry were married on may 26, 1995, in nantucket, massachusetts. <SEP> on april 18, 1985, a few months after taking his senate seat, kerry and senator tom harkin of iowa traveled to nicaragua and met the country's president, daniel ortega. though ortega had won internationally certified elections, the trip was criticized because ortega and his leftist sandinista government had strong ties to cuba and the ussr and were accused of human rights abuses. the sandinista government was opposed by the right-wing cia-backed rebels known as the contras. while in nicaragua, kerry and harkin talked to people on both sides of the conflict. through the senators, ortega offered a cease-fire agreement in exchange for the u.s. dropping support of the contras. the offer was denounced by the reagan administration as a "propaganda initiative" designed to influence a house vote on a $14 million contra aid package, but kerry said "i am willing..... to take the risk in the effort to put to test the good faith of the sandinistas." the house voted down the contra aid, but ortega flew to moscow to accept a $200 million loan the next day, which in part prompted the house to pass a larger $27 million aid package six weeks later.
