If Barack Obama sweeps to victory in the US presidential elections next month, it may be partly due to his secret weapon - Jewish grandchildren.

One of the more weirdly named support groups for the Democrat nominee for the top job is "Jewish Grandchildren for Obama", which was set up, according to its blurb, to "help educate older generations of Jewish voters about why Obama is the best choice - domestically and internationally".

But why stop there? We could have Jewish nieces for McCain and perhaps even Jewish kilt-wearers for Brown.
