I don't think that 81% of them who voted for Trump were necessarily all that way as I know some of them personally that weren't enamored with Trump but voted for him for other reasons.
However, at this point I will have to say that if they still support Trump and Moore, they've compromised their supposed Christian faith into oblivion. No one can truly believe in what Trump has said and done and have that somehow miraculously match what Jesus said and did. At this point, it's clear that it's either one or the other.
BTW, the last poll I saw on this had Trump's approval rating with Evangelicals drop down to the 60% range, but that was taken a few months ago.
