Conservatives of a libertarian bent are likely to feel quite welcome, and AFAICT have always been well-represented.
as far as I've seen, a global job market has resulted in more exploitation than prosperity. Most of the profit seems to go to international businesses that have little interest in giving back to their host nation in the form of jobs or taxes.
Now there is a term I never expected to see.
That's not entirely a coherent combination of labels; the closest thing in the real USA to that seems to be bog-standard conservatives who selectively deploy libertarian rhetoric against programs they oppose.
what is incoherent about it? Both libertarianism and nationalism are vast repositories of political thought that can be combined in any number of ways. Libertarianism at its core does not require forfeiting national interests, nor do national interests require forfeiting a global economy founded on capitalist principles.
The reaction to Trump's executive order actually seems to personify the inherent conflict between the two sides -- while a lot of conservatives (including, I would say, those with more nationalistic viewpoints) approve of the executive order, the libertarian side so far seems to be pretty vocal about their disapproval.
I think the assent/dissent situation around Trump is a lot more complex than "conservatives for, libertarians against", precisely because his platform consists of a mix of ideological positions. He has almost nothing in common with neoconservatives (which seems to have been a big hitter for public appeal), and both conservatives and libertarians seem to differ depending on their concern for specific libertarian policies. Hence the fracturing of the GOP, with as many representatives condemning him as supporting him. After all, the GOP is nothing if not a grab-bag of varying political positions.
Compare Donald Trump to Ron and Rand Paul, which are the prime examples of what libertarianism is (unlike Gary Johnson), there is a lot of overlap: free market healthcare, strong borders, deportation of illegal aliens, deregulations, tax cuts and tax code simplifications. There are disagreements on free trade (and please note that TPP is "free trade", not free trade) and NSA spying.
As for Pauls being conservative, as long as they are not using government power to force you to be like them it's all fine in my books.
