By your question I’m left to assume you are going somewhere, so I’ll say Trump has NEVER had a duty to DO anything conservative, anymore than any other Joe. He has expressed conservative ideals at times when the subject was breached. Now that probably doesn’t meet your or others idea of whatever some ‘consistent’ conservative might be, but again he has never had that duty. I’ll take it to the next level and say his proposed policies are more conservative than ANY I’ve seen since Reagan and if he can accomplish even one or two of those proposals, The Wall and deportation of those bent on harm, I’m good with that. I’ve listened to the same talk of conservative nature out of hundreds and hundreds of men and women who actually did have a duty to perform, and all & all they have one and all failed miserably. Hence the rise of Trump. Thanks for cordial question (I think).
No he never had that duty. But anyone who calls him a conservative does have a duty to evaluate him based on what he’s done. Not what he said he’ll do.
He’s supported liberals all his life.
