That's not what all the polls about General Election voting intention are saying Ludwig

They're saying that UKIP will pull 14% (more than the Liberals) because of the spread of that though they're not likely to gain more than a few seats - current predictions are a 90 seat Labour Majority.
The Tories will continue to say that a vote for UKIP is a vote for Labour and that will have some impact but there's a lot of ground to make up.
The problem remains the age old Tory problem that they are split with right wing Tories bleeding off to UKIP
They've not been united for 25-30 years
