Are the Tories in landslide mode?

We’ve just uploaded the content from the latest magazine on to the website, and I’d suggest you read Fraser’s politics column ahead of the results from Crewe and Nantwich tonight.  In it, Fraser writes of how the Tories are unofficially shifting to a “landslide strategy”.  They now regard a whole host of marginal seats as “in the bag”, so party resources, cash and effort are being diverted to those seats which were considered “unwinnable” before Cameron took charge.  Crewe’s something of a pilot for this approach, so the result is of extreme importance to Cameron & Co.  What do CoffeeHousers make of the strategy?  Is it a masterstroke?  Or a risk too far?  As always, have your say in the comments section.
