Unfortunately not. The sad fact is that no amount of money or organizing can change the fact that some places just don't have enough people who aren't neck-deep in QAnon and are willing to vote for Democrats.
So what are Tennessee Democrats trying to do with this gun stuff, because they are only winning Shelby, Davidson and maybe Haywood or Hardeman on a good day...they can't even win Dolly's Sevier County....
Not exactly notable that Sevier isn't voting for Democrats. It's East Tennessee, which has been ridiculously red for the better part of the last century.
