According to early reports, voter turnout this year looks immense. So, US readers, remember:

If you are planning to vote after work today, or late in the day, they MUST let you vote so long as you ARE IN LINE by 7:30 p.m. when the polls close. Do NOT let them turn you away if you are there but still in line, whether inside or outside the polling location.

Don’t make the mistake of thinking you can’t make any difference. The presidency was won last time by just 537 votes. It is your right and it is your duty to take part in the democratic process – especially at a time when the US is claiming to be spreading democracy around the world. Set a good example, and keep this election clean.

Please?

Update: Oh dear, the BBC is reporting that electronic voting machines in Kerry-leaning swing-state Pennsylvania already had votes logged on them when polling opened this morning. There may already have been a legal challenge…
