Vice Pres. Al Gore played the good environmentalist yesterday in New Hampshire, designating the Connecticut River, which winds through four New England states, as an American Heritage River and announcing that $819,000 will go toward projects related to the river. Gore canoed along the river with New Hampshire Gov. Jeanne Shaheen (D), as friends, backers, and reporters paddled along in their wake. Gore said, “If you don’t want a president who will be committed heart and soul to moving heaven and earth to clean up the environment in the right way, then vote for somebody else, because that is what I will do, and I want people to support me on that basis.”
