There’s no real substance behind the idea that this guarantees a red victory. No Democrat who was against Trump before is going to realistically change their view over Trump over this situation. It doesn’t change who Trump is or what he stands for. If this achieves anything, it will be to incite violence.
You’ll also take notice many of the accounts parroting this nonsense are not old accounts. Usually, these accounts were just botted to repost news articles or memes and only just recently started commenting. It’s a strange pattern I’m seeing across multiple threads.
