To be honest even though I do not vote and I am politically neutral, I have much common ground with the Cornerstone Conservatives Jacob Rees-Mogg, William Hague, Boris Johnson, Peter Bone kinda guys.
There not polling anywhere near enough in the constituencies for that number of seats. Check out Lord Ascrofts polling. Carswell might have a better chance than Reckless though as he is more popular an MP in his constituency.
Lord Ashcroft is a Conservative and it is in his interest to poll UKIP low. If he can cause people to think UKIP have no chance in their constituency, he can convince many Ukippers to vote for the Conservatives.
I think many people underestimate UKIP's support in the North. I also think UKIP might get one seat in Scotland.
