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....
Sevier County has not voted for any Democrats since Andrew Jackson in 1832 and was safely Republican (...and before that Whig) even in the days when Tennessee as a whole was safely Democrat; this
really means nothing.
