991 people were polled:
87% thought Alex Salmond won the debate;
7% thought it was Annabel Goldie;
5% thought Iain Gray was the winner;
and 1% thought Tavish Scott.
Over half the respondents (53%) found their view of Alex Salmond became more positive during the debate, but nearly three-quarters (74%) found their perception of Iain Gray changed negatively.
Annabel may have done herself no favours over university tuition fees, but despite that, she was seen to be the next best thing to Alex for FM.

Mr Scott has been stabbed in the back by London Liberals. Not only has the windfall tax on oil companies cost Scotland billions in investment, there is an estimated loss of 40,000 jobs to take into consideration. Maybe not all at once, but that’s a lot of employment and a lot of salaries to be spent!
It was, of course, the decision of George Osborne to levy this tax, but in some mad lemming like bid for notoriety, or to curry favour with Mr Cameron so that he may progress in the ranks of Cabinet ministers and get his own department (they may be looking around for a new Foreign Secretary soon), Danny (ginger rodent*) Alexander has claimed full responsibility for dreaming up the tax.
This may have been a tad foolish given that the biggest losses will be felt in the town of Aberdeen, where there is one now very vulnerable Liberal Democrat seat for the taking.
Iain Gray: read ths and weep.
Hey ho, isn’t politics interesting?
*allegedly (if in doubt refer to Harry Hardwoman)
PS: Top marks to Annabel for wearing a dark inobtrusive suit, like all the men necessarily had to wear. Whatever people say about her, and the Tories' policies, Annabel still strikes me as a decent sort.
