No.
Richard Spencer hates conservatives and is very open about it. He has said, over and over, that to be mistaken for a "Conservative" would be one of the most horrible things that could happen to him.
He's an evolved libertarian, a white nationalist, an atheist, favors socialized medicine (for the nation, not for a multi-cultural entity), and a lot of other things.
Lots of people in politics pretend to be conservatives, but Mr. Spencer does not.
He sounds like a Randian who has a touch of 19th Century anthropology thrown in.
So he does not claim to be a Conservative, yet the far left calls his group the "alt-right" and uses that to attack and smear all Conservatives?
I do recall that the left was trying to denigrate the "alt-right" prior to the election as a means to try to erode support for Conservative ideals. As far as I could tell at the time, the "alt-right" was nothing more than Conservative ideals taken on by young internet-savvy people. In fact, as far as I know, the "alt-right" is still the young people's brand of Conservatism.
This whole thing about Spencer still makes me think he is a leftist mole.
