You don't get to have a "perfect" candidate. Most of the time, your choices are between which choice you dislike the least. And when the choices are between Harris and another 4 years of Donald farking Trump . . . well holy jumping shitballs . . . that should have been the easiest choice in the world.
Fark EVERYONE who made this possible. And enjoy your precious little "protest vote" Dems. This is your fault, too.
The only other explanation is that those 14 million Democrats DID vote, but that their votes weren't counted due to election day farkery. But I'm not ready to go down that rabbit hole without solid proof.
