They didn’t win more seats because of the brainless people who are programmed to vote Democrat without thinking of the damage that it’ll cause and because it’s easier to vote Democrat than to get a job, raise a baby that you don’t want, stop committing crimes, get psychological help if you’re attracted to someone of the same gender or paying off student debts for degrees that won’t pay for themselves such as gender studies.
It may work in the short term for those who voted Democrat but it’ll hurt them in the long term.
I’m very confident that if there was an exam requirement to vote (that showed that the voter knows what each party represents) the outcome would be different.
