We have come up with a unique way for non-Americans to express your views on the policies and candidates in this election to some of the people best placed to decide its outcome. It's not quite a vote, but it's a chance to influence how a very important vote will be cast. Or, at the very least, make a new penpal.

It works like this. By typing your email address into the box on this page you will be sent a name and address of a voter in Clark County, Ohio from the most recent publicly available voters roll. You may not have heard of it, but it's one of the most marginal areas in one of the most marginal states: at the last election, just 167 votes separated Democrats from Republicans. It's a place where a change of mind among just a few voters could make a real difference.

Writing to a Clark County voter is a chance to explain how US policies effect you personally, and the rest of the world more generally, and who you hope they will send to the White House. It may even persuade someone to use their vote at all.
