Crikey, this is a weird thread. There are a lot of outdated, surface stereotypes here.
I am from a very political family (with close family members that belong to different parties: LibDem, Labour, Tory, Ukip and Green) and do a lot of cross party work. You get diamonds in every party. You also get absolute shits in every party. And just because someone is in a particular party or votes for them does not necessarily mean they vote for or support policy that adheres to what you would presume are national party perspectives.
You get Labour voters that have an understanding of race relations that seems to come from the 1950s, and hardcore Thatcherites demanding grants for council estate community associations. It really is not as simple as "a Tory" or "a Labourite" or a "LibDem" or "Ukip" or "Green." In reality, those labels mean very little.
Indeed, if you were to blind interview quite a lot of the politicos I know and then guess their party, you would probably get it wrong about 75 percent of the time.
And that, to me, is key really. It's not where you sit on the traditional left/right spectrum but also where you sit on the axis of authoritarianism to libertarianism, and also where you situate yourself in terms of economy, society and culture and where your parameters are for each. You can get extremely socially and culturally liberal Tories and downright almost totalitarian Labourites.
Again, there's a lot of difference, for example, between the late Bob Crow and Chuka Umunna -- yet both were/are Labour. I could, personally, have had a fair few pints with Crow, but I doubt I could cope with Umunna for a second.
Things have shifted massively in politics over the last thirty years, and the scene was always very complex anyway. The local councillors in my borough that are gay are all Tories, for example, and one of them advocates strongly for the rights of the disabled (he is one of only two councillors to do so; the other is a LibDem). Most of the women councillors are Tories. Some of the longest standing councillors are female Tories.
My personal measure is: are you a twat or not? My current mental leaderboard of twats is headed by five Labour councillors, two Libdem activists, four Tories (one of whom is an MP) and two Ukip members. Believe me, in terms of twattery, there really isn't much between them, despite the fact they are from four very different parties.
