Debate 2: What a difference a week makes
We moved from "I agree with Nick" to "I disagree with Nick" as Gordon Brown and David Cameron attacked Nick Clegg tonight over Trident, immigration and MPs' expenses.
The prime minister was more confident and, above all, more aggressive than last week - he warned that David Cameron was a risk to the economy and Nick Clegg a risk to security. There was more of the passion which his party craved.
Gone were David Cameron's obvious nerves. But if his supporters had been hoping that he would be more aggressive, they were to be disappointed - save for his anger at what he called "scare stories" peddled by Gordon Brown. He was determined, it seemed, to look and sound ready for office, speaking again and again about what he would do "if I were your prime minister".
Nick Clegg could not, of course, repeat the novelty of his first appearance. He appeared to want to add policy detail to the anger he expressed last week.
A week ago, the polls declared that there was one clear winner. So too did most neutral observers. This week, they seem to confirm that we are genuinely now in a three-horse race.
