For 2018 election strategic purposes Democrat's likely want Moore to win and Republican's probably would be better off strategically if Jones wins. If Moore wins every Republican will be attempted to be morphed into Moore in 2018.
I still think Moore will win. Statewide elections since 2008 have been around 60%/40% Republican to Democrat. Some Republicans will stay home and I expect the Black turnout will not equal past turnouts when Obama was on the ticket.
My guess is Moore will get more than 50%, maybe 53% to 55%. Write-ins maybe 2% and Jones around 45%.
If Moore wins and Franken does not resign the benefit to Dems pretty much goes away in 2018.
