See post 53. If you're seriously comparing the Democrat party of 40-50 years ago with today's Democrat party, you've completely lost the argument.
Your original post said “once a democrat, always a democrat.” It didnt say “nowadays, once a democrat, always a democrat.”
Quit trying to pretend like you meant something you didnt say. Plus, how do we convert people if we wont allow former democrats to join our side?
