The word conservative is pretty hard to define. There are many different shades of political conservatism and all are not equal. For example, the types of conservatism espoused by the Democratic Labour Party with it's Catholic routes (or those remaining remnants of the blue collar conservative ALP faction that haven't yet been purged from the party) is quite a different form of conservatism than what we would see coming out of the L/NP and very different to what we see from a party like One Nation. And the US would have similar themes running through it.
Certain conservative factions have embraced him. But for others he is the antithesis of conservative values. I'm a pretty conservative person, but from doing a bit of reading on the subject recently, probably find myself closer to what is called in the UK, "Blue Labour" conservatism. So have always been uncomfortable with the rise of Trump. I'm probably one to say he is the antithesis of my version of conservative values. But at the same time I place some blame on the liberal establishment for a not insignificant contribution to creating an environment for 'Trumpism' (for want of a better description) to rise as a reactionary force.
Another note on a bit of a tangent. The movement has it's roots further back than Trump. The fire was really lit during the Sarah Palin VP campaign. Trump was simply a continuation of that movement. For a bloke respected on both sides of the aisle, that was a serious lack of judgement from Senator John McCain to select Palin as his running mate. He was a conservative who detested Trump (and Trumpism), but ironically played a major roll in lighting the flame.
