That is an area where the dems will try to read too much into it. This was a referendum on Moore, not Trump. Since the presidential election, Alabama voters move even further to the right by going with Moore rather than Luther, and then since then they many rejected moore due to their conservative values, not because they have become more lib.
The dems scored a victory, but dont kid yourself, it was due to Moore's problems and if the national election were held again tomorrow, Trump would win even bigger there. Luther Strange could have beaten Jones with very, very little difficulty. And Jones did not really get the "Clinton vote" he got the got the dem vote and Clinton was dem too.
Even Shelby, the other republican Senator, said he would not vote for Moore. The dems caught a highly unusual break and used it well. Don't get giddy just yet. Alabama is going to be looking for the first chance it gets to put a republican in there again and the voter base is a sea of red. Dems should be out there working every day though to improve the lives of blacks and other constituents rather than just taking them down off the shelf at election time. Try that for a while and if you make progress, well good then. Try earning it the old fashioned way like that.
Maybe, maybe not. I never liked this election as an indicator for a bunch of reasons but this was not an election where voters were turned off and turnout was low. turnout blew the doors off expectations. The consensus was 20-25% of the electorate would show up and it turned out to be 40%.
I’m not so sure Moore underperformed. He got a lot of votes and may have hit his target numbers. maybe he needed to overperform and couldn’t.
