Yeah... no.
I think a party that has resisted socialised healthcare and then attempted to scrap even the half-hearted halfway house someone struggled through is a big sign screaming "Off Limits" to my political sensibilities. I don't believe in tax cuts for the rich, and endless military spending. I don't believe in subsidising oil companies up the wazoo and aggressively resisting environmental policy. I believe in active intervention by the state to improve poor communities and overcome institutional barriers to human development, not lack of action defended with waffle about "American Dream" and pulling up by the bootstraps. I'm in favour of free movement, which I might grant the Republican Party some leeway on in that their actions have largely not met their rhetoric. I'm disgusted by the prevalence of hostility to and impedence of disadvantaged groups in favour of 2000-year-old notions from their holy text of choice.
If we mean "conservative" specifically, I am not completely averse to conservatism. I do accept the principle of if ain't broke don't fix it as viable, and I do see that societal instutitions and traditions can have value, and so on. On the other hand, I don't think that's conservatism, it's pragmatism. My stance on conservatism is akin to Hayek: it's only as good as what it conserves. I don't think something merits any inherent priority because "That's the way we're used to doing it", and if I do not offer traditional customs any privilege, have no ideological drive to keep the status quo, I cannot meaningfully be a conservative.
I'm totally prepared to accept that the Republican Party will have at least some voters who are not so far from me who made their decision for whatever reason. However, I would probably be asking them why on earth they support it when there's a party evidently much closer aligned to their beliefs, and secondly they are not the party but its fringe and not a reflection of the general stances of US conservatism. The party is, as far as I am concerned, a non-starter on numerous levels and I am not a conservative.
