The party or the voters?
The former are largely people who want power,and will do or say anything they can get away with to get and keep it: any donation, any lie, any favour, any promise, any policy. There's essentially no coherent ideology or principle: It's all just power at any cost. Labourites,of course, are also power hungry, but are more likely to view power as a means to altering society (to a greater or lesser extent) than an end in itself.
The latter are, as always, more complicated and diverse. Tory voters tend to believe in limited public spending, limiting taxation (though usually are not too bothered about surveillance or civil rights). Tend to be a bit closer to the centre, tend to be more traditionalist in outlook. Tory voters are usually suspicious of Labourite/left-wing aims to change society, regardless of how tepid or radical these actually are. I think it's probably fair to say that an average Tory voter views this as an illegitimate, dangerous or wasteful use of power. In terms of "profile", they're likely to be homeowners, to be older, and to be white - but these are of course complete generalisations and tendencies rather than cast iron rules. They're also less likely to have degrees (because degrees were rarer in the past than they are now).
