Moore +3 is not a good result for Republicans, no matter how you slice it. Keep in mind that their last poll had him up by 6. This race is very winnable for Democrats.
Obviously it's a bad result for Republicans considering it's Alabama. Even before being exposed as a pedophile Moore was going to underperform generic R in Alabama, but that just made it go from an embarrassing underperformance to an absolutely pathetic underperformance. But he's still inevitable. ~30 points is quite a lot of padding, especially in these polarized times.
Also, looks like it's time to add to the "People Democrats can't beat list":
A guy who forced his mistress to get an abortion
A guy who defrauded Medicare for billions of dollars
A guy who bragged on tape about sexual assault and grabbing pussies
A guy who bodyslammed a reporter
NEW EDITION! A literal pedophile
But remember, It's All Hillary's Fault™! Also, Kelli Ward is guaranteed to lose because she believes in chemtrails or something.
