My fellow non-Americans ...

Guardian Unlimited | US elections 2004: "The result of the US election will affect the lives of millions around the world but those of us outside the 50 states have had no say in it - until now. In a unique experiment, G2 has assembled a democratic toolkit to enable people from Basildon to Botswana to campaign in the presidential race. And with a little help from the folks in Clark County, Ohio, you might help decide who takes up residence in the White House next month. Oliver Burkeman explains how

Ohio is one of the most crucial swing states: Kerry and Bush have been campaigning there tire lessly - they've visited Clark County itself - and the most recent Ohio poll shows, once again, a 1% difference between the two of them. The voters we will target in our letter-writing initiative are all Clark County residents, and they are all registered independents, which somewhat increases the chances of their being persuadable.

Several of the ideas described here can easily be applied across the US too, though, and we have provided further resources on our website for this purpose. While there's no point being coy about Britain's preferences in this election (never mind those of Guardain readers) - a poll last month put backing for Kerry at 47%, against 16% for Bush - we have included information for supporters of both main candidates.

"Perhaps the most important way foreigners could help John Kerry would be to help out those organisations which have, as part of their mission, fostering African-American voter turnout," says Nathaniel Persily, a Pennsylvania university expert on election law. "It's quite clear that if there was 100% African-American turnout in Ohio, Pennsylvania and Florida, John Kerry would win this election running away." The National Association for the Advancement of Colored People is the most obvious choice here - an influential, well-organised, non-partisan body whose get-out-the-vote activities are extremely likely to end up helping the Democrats.

"On the Republican side, it would be the Christian conservatives," Persily adds. "[Bush adviser] Karl Rove has tried to register four million additional Christian evangelicals, and if they all turn out, then Bush wins." The leading option here would be the Christian Coalition, which describes itself as "America's leading grassroots organisation defending our Godly heritage".
