The Tories are fundamentally the Party of Property. Ultimately it is in their best interests to reflect whatever the values and views are of those who own it.
..such is why they've been doomed never to crack 36% since 1992, and will be so doomed again, yes?
as a total outsider ignorant of British politics the meteroic rises and falls of BNP, UKIP, etc would suggest the Tories have room to move their rhetoric to the right on immigration, Euroskepticism and so on and as such constitutes failure to capture an element of the 'far right' vote. no majority in parliament in 5 consecutive elections seems like a colossal failure of long-term strategy.
facially (again, I'm no expert) similar to the problems the US Republicans have in expanding their base beyond whites, allowing the Dems to turn Latinos into a 70% (D) demographic, etc. the US GOP only does well in Congressional elections because the game is rigged.
