How much more confirmation do traditional Tory voters need that the party they support is no longer conservative than the fact that Cameron is prepared to work with the Lib Dems to form a government?
And how much more confirmation that the three main parties are all the same than the fact that the same party that Cameron is prepared to work with is also prepared to work with the Labour Party?
The only reason Labour and the Tories aren't prepared to work with each other is the traditional enmity of their supporters.
Face the truth Conservative supporters - the party you support do not support your values anymore. The Tories are the same as the Lib Dems and the Lib Dems are the same as Labour. There is no conservative party for you to support anymore.
So stop voting for them.
