Palin back in the picture

Sarah Palin was back in the limelight with a speech to Tea Party conservatives in Nashville over the weekend, during which she poured scorn onto the Obama administration and fired up her audience, who chanted "run, Sarah run" according to an article in the Guardian. Palin seems to be the thorn in the side of the democrats in the US and there is no sign she is going away anytime soon, apparently hinting at a potential 2012 presidential challenge.
