I agree with their education policy (especially grammar schools) and a lot of their criminal and immigration policies. I have done the "isidewith" quiz (uk.isidewith.com/political-quiz) and I side 58% with Conservatives, 48% with Labour and 40%, 36% and 34% with UKIP, LibDem and the Green Party, respectively. But in general I have done it because it seems to me that the Conservatives are clever people (mostly Oxbridge educated), and you have to trust the leading of a country to clever people. (We all remember a certain Labour prime minister and his "bigoted woman" remark, when he thought his mic was off, don't we?) The Tories support working people, as opposed to second- and third-generation lifelong benefit claimers (large estates of high deprivation in my region) and they have already proved themselves by decreasing unemployment levels to those in the 70s, if I remember well (I wasn't in this country then, I'm an immigrant).
Disclaimer: I mostly use MN at the weekends, so I will come back and read replies today but I can't promise anything from Monday onwards...
