The arsonist in this scenario would be the corporate Democrat consultants and Kamala herself. You run the same campaign in 4 more years and you’ll get another Republican. It is time for self-reflection and people to demand change in the Democratic party. Failing to do that is exactly why Trump got re-elected.
It isn’t subjective. Voters will tell you why they didn’t turn out or voted third party. The economy is important, but Harris turning to Mark Cuban to push establishment messaging wasn’t a good selling point either.
