It seems from this poll in The Times that voters are not impressed by Gordon Brown's attempts to make a distinction between Tory spending cuts and Labour investments: Cuts
Most voters are canny enough to realise that whichever party is in office, there are going to have to be big spending cuts, particularly after today's news about big falls in tax revenues. That isn't to say, of course, that there would be no difference in the size or scope of the cuts depending which party formed the government.
There is also a difference between expressing a view in favour of hypothetical cuts in a poll and experiencing those cuts in services that a voter use. But the Conservatives are already taking a perverse pride in being the most unpopular party in history within six months of being elected.
