So far all the American people know about Kerry is that he was in Vietnam, he's rich, and he's not George Bush. That won't cut it in November, no matter what Bush's approval/disapproval numbers are on election day. The Democrats' biggest worry isn't whether or not enough people approve or disapprove of the candidates' stated positions on the issues - it's whether or not Kerry can fire up the troops, and motivate Democratic leaning constituencies to get off their butts and go vote on election day. It's all about turnout. If you have what it takes to inspire your supporters to turn out in sufficient numbers, you win. Keep in mind that only about 50% of American adults bother to show up and vote in Presidential elections.
