Some people have noted, Trump is largely preaching what Pat Buchanan did in 1992, what is in a lot of Pat Buchanan's books. Whether that has a libertarian appeals.
Some Libertarians, Ron Paul types, appreciate Trump's message because it is largely about re-shaping the government, I don't want to say "tear it down"; but others might. Trimming the government down, smaller government. Rush said that just in the last two days.
I guess Rush, ex-Reagan staffers, 220, Gingrich, Buchanan, all of the supporters of Trump, etc. don't fit the conservative mode, oh, and Bob Dole too.
