The Republican party's post-election downward spiral continues with aides of John McCain saying that Sarah Palin did not know Africa was a continent.

Fox News anchor Carl Cameron claims McCain's aides told him Palin did not understand Africa was a continent, not a country, and that she also didn't know what countries were in the North American Free Trade Agreement [NAFTA].

Cameron says the source told him that Palin had no idea the US, Canada and Mexico were in NAFTA.

The Daily Mail reports that McCain's aides also said that she spent "thousands more" than the reported $US150,000 on clothes during the campaign, much to the shock of the donor that footed the bill.

Other allegations to surface included the former vice-presidential candidate and Alaska governor answering the door to McCain's aides in just a towel.

She also reportedly threw tantrums over negative media coverage.

These reports spark further speculation there is serious unrest within the Republican party since it's presidential defeat on Tuesday.

Palin was under fire throughout the campaign after encountering numerous speed bumps, including her expensive wardrobe, not being able to name a newspaper she reads and being the subject of the now infamous Saturday Night Live sketches featuring Tina Fey.
