The conservatives have already lurched heavily to the right, pulled in that direction by UKIP and their ilk. Its now a party where the likes of Soames and Hammond no longer feel they have a place, where former Conservative PMs campaign against the current PM.
I also find it is said, completely unironically, by people who I imagine have never strayed from their normal voting patterns. I remember your displeasure at the Conservative party voting against legalising gay marriage and Cameron having to rely on the labour party to pass the bill, vowing never to vote Tory again.
Yet I have a rather strong suspicion that you did not vote for Blair, who is realistically as centre ground as labour are going to get without crossing the benches and just becoming Tories. I suspect most of the people on this board, which for whatever reason leans incredibly right wing, have barely graced the labour boxes in GEs in their lifetimes.
After 9 years of austerity from the current party and coming across voters who voted for 'change'...by voting for the incumbents, I'd say the majority base their decisions on wilful ignorance and important things like how graceful the leader looks while eating a bacon sandwich.
