can you tell me what currently elected politician is a true conservative?
Not really.
Conservatism isn't a political ideology, it's a framework of doing things and a way of thinking, and it is rather difficult to tell if someone makes decisions that fall within that framework because they are Conservatives, or if they have other reasons for doing so. Most people who call themselves Conservatives have never read Conservative thinkers. To them it is merely a convenient label, whether intended to take a stance against their Liberal neighbour, or emptying their customers' pockets. Nor can someone be "very" Conservative or "slightly" Conservative. You either think this way or you do not, there is no "very" or "slightly" about it.
So I can't tell you which politicians are Conservatives or not.
What I can tell you, is that Conservatism rejects utopianism and absolutism.
What this means, is that while socialism has a recipe for creating the utopian society, and will follow that recipe whether the target society is an eskimo village or a mining town in Pennsylvania, Conservatism may take routes to improve society that differ wildly from one setting to another. Conservatism looks at the ingredients before selecting a recipe.
Conservatism is neither individualistic or collectivist, and neither authoritarian or anarchic.
It demands that people work together, not because working together is a goal in itself, but always for a reason and always limited to that. For Conservatives, the tale of Cincinattus is a heroic story, while the story of Caesar is a tale of caution. Conservatives will applaud individual freedom but may yet demand military conscription. "If it's stupid but it works, it ain't stupid" might be one Conservative catchphrase, but equally so is "If it's brilliant, but can never work, it ain't all that brilliant".
Conservatives are wary of dogmatism.
In Conservatism, good hierachies run by bad people are a recipe for disaster; bad hierarchies run by good people improve over time if allowed to do so. In the long run, people are always more important than method.
Thus Conservatism will sometimes support monarchies and sometimes oppose them. Sometimes it will support religion and sometimes oppose it.
Conservatism is belief with cynicism.
Some people have called Conservatism "Liberalism with quality control", for historically it is a branch of Classical Liberalism. Conservatism is so named because it's purpose is to safeguard the rewards that Liberalism won us. It became so because mainstream Liberalism tended to end in bloodbaths since it was way too easy to forge into despotism. Conservatives believe in the betterment of humankind, but roll their eyes at anyone who claims to offer it.
Conservatism has many parents.
Burke and Hume are the two who are most often mentioned as fathers of Conservatism, but it is inspired by thousands; from Hammurabi to George Washington.
Conservatives do not have a chief ideologist or any political manifest. It wouldn't make much sense when the whole point is to recognize and deal with human diversity and imperfections.
And finally, Conservatism demands you be smart enough to know, that the question asked is not always the question asked. Same applies to answers given.
