imo, the most interesting part of this poll is that people are much more likely to trust Doug Jones than Roy Moore (58-30) on LGBT issues. That's... remarkable, to be honest. Given poll numbers at the top of the poll, it suggests that a Democrat could use LGBT issues to draw voters to support him. In Alabama. Let that sink in.
It may reflect that Alabamans see Roy Moore as too extreme on and obsessed with gay rights, even if they don't approve of gay rights. Maybe they're sick of him breathing fire about gays all the time. Most recently he was in the news for blaming gays for the allegations against him.
I'm not saying that I think Alabamians are all waving rainbow flags now. Rather, I think that this interpretation is more correct - even folks from Alabama (even Roy Moore voters!) think that Roy Moore has gone too far. Doug doesn't need to talk about his support for LGBT rights, but I think he could make hay saying "why does Roy Moore keep carping on about this rather than talking about the issues that matter to us?"
