Christians and members of any religion have an absolute right to support whomever they want for whatever reason.
But it floors me 1) that anyone in their right mind believes that that guy gives a sh1t about Christianity and 2) that anyone believes that "America first" is a platform compatible with what Jesus was supposed to have preached.
Think about Jesus. Then think about a (supposed) multi-billionaire arguing to deport millions of desperately poor immigrants whose family relies on the pittance they receive here. And put up a literal wall to keep them out. And the millions of desperate people trying to escape starvation and violence elsewhere who want relief, and who this billionaire says he doesn't trust.
We're all hypocrites in some way or another. But most Christians will say Jesus' philosophies are the most important thing in their lives. And there are millions of Christians who immediately contort or forget those
very fundamental philosophies if they don't fit the political positions of their candidate.
This is a good article about the subject.
