Not being in the US, I can escape the onslaught of political advertising that some people (those in closely-fought states) are experiencing.
Given that I'm not an undecided voter and have already cast my ballot, such things would be a bit redundant for me anyway.
But a couple of things I've caught online have struck me as being quite effective.
First, a 'no on Prop 8' ad from California. (This is one of the many 'ballot initiatives this year in many states, and in this case it revolves around the issue of gay marriage. In short: 'no' is in favour of equal rights, 'yes' is against.)

The new ad is both entertaining and powerful:
