Cain takes centre stage
Last night may well have been the moment Rick Perry's hopes of winning the Republican nomination finally ended. Having already seen his polling surge rapidly reverse - largely because of poor performances in the last two debates - he put in another poor performance as the candidates clashed in New Hampshire. Worse, he followed up the debate with an American history gaffe, saying: "actually the reason that we fought the revolution in the 16th century was to get away from that kind of onerous crown if you will". As a result, he was subjected to merciless Twitter mockery, via the hashtag #perryhistory. It's taken him a month to go from frontrunner to national joke. But, as I've said before, Perry's loss is Cain's gain.
