There are two issues here: Whether Alabama voters actually believe these allegations, and, if they are true, whether so much time has elapsed that they have no bearing in the quality of the candidate today and the people would be willing to relegate any bad behavior to the past and vote for today's Roy Moore. Both have significant impact on how voters will vote and whether Republicans will win or lose that seat.
No one can really say for sure what's on the minds of Alabama voters, especially the pollsters who, like many of us have never been to Alabama before. Oh, they can ask their leading questions, thinking Alabama voters are all a bunch of country bumpkins who will give the pollsters the unfavoranle answers these pollsters are looking for. Maybe they will tell the pollsters what they want to hear, but then vote the opposite. That vote on election day is the only "poll" that really counts.
But if Moore loses and the Dems take Alabama's senate seat, there is plenty of blame to go around. A goodly chunk will fall to the Republican party itself which may actually be willing to let the Dems take the senate seat because they are still pizzed that their establishment candidate lost to Moore. Who knows? Maybe these allegations against Moore came from Republican operatives, not Democrats. But regardless of who is behind these allegations, the Republican party will bear the blame for Moore's defeat because they abandoned him and let him hang out to dry instead of giving him their support. Why did they not demand real proof of these allegations?
As said, a lot of your questions are answered in the Hannity interview and as I read in one article, Moore could not have had a more friendly interviewer than Sean Hannity.
Even if one discounts the 14 year old's story which I am, there are other questions. The scenario itself is now suspicious.
"Oh, Moore did not do this with the 14 year old but he doesn't deny pursuing high school girls" That doesn't wash well.
And as another post suggest, I guess one could say that Moore went to West Point, then served and then, came home at 27 years old and because of the time away, decided to pursue girls in highschool. I suppose. A lot of people would possibly, try to find females elsewhere, such as a church or something.
Per Roy Moore's words "I dated a lot of women", so it doesn't sound like the "women over 20 are in short supply" line isn't necessarily true.
I was for Moore until the Hannity interview. I think he came off real bad in it. But it is a month until the election, so we all have the prerogative to change our minds over and again.
