1) No, the conservatives have not always been guided by the bible and the constitution. And to suggest such is pure delusion or ignorance of history and the present.
2) Anarchy and socialism aren't "leftist themes" any more than they are far-right themes. Just more delusion.
The bible is a hodgepodge of contradicting themes, which religions of many denominations latch onto when they are convenient, and conservatives are no different. The bible has guided their ideology no more so than any given politician. And if the bible guided it this year, Trump wouldn't be the nominee. As far as the constitution, do you realize how many GOP-backed laws have been struck down in federal courts over the past 2-3 years?
