What do "conservative" beliefs mean any more?
The pro-Russia stuff would not be a conservative belief historically. Neither would be massive tariffs, bypassing Congress with impoundments and executive orders, pulling funding from research institutions, threatening the fed chair's job, erratic and ever-changing policy announcements, using the office for personal enrichment, lying about election results/fraud, etc.
Could you imagine how Reagan/GWHB would react to any of the above? I'd say very few of Trump's policies align with conservative beliefs -- at least how conservative beliefs have traditionally been defined and understood.
Being an immigration hardliner and cracking down on racial diversity would certainly qualify as traditional conservative beliefs
