The Republicans are running low on ideas

Last week's John McCain adverts - which basically were 'oh, you all love Obama, why don't you marry him if you love him so much' - seemed pretty weak.

But there was a further down to go. The latest Republican advert runs through the following logic:

Obama is really popular.

Britney Spears is really popular.

Therefore, voting Obama is like voting for Britney Spears to run the country.

Yes, that'll work. I now really believe that Obama will be sworn in wearing a skintight pleather catsuit.
