While I can appreciate the opinions of those who find the idea of foreign nationals contacting US voters in a key state appalling, I assure you that it will have no effect on the current election.
If the Democratic and Republican jauggernautic machines are unable to effectively persuade the populace of said states with the $400 million that they have on the books for campaigning in this election, a Belgian dairy farmer's e-mail is not going to ruin our democratic process.
In addition, the recipeints e-mail filter, whether it be software or cerebrally based, will most likely pick it up as spam.
Just my humble opinion...
