The only reason I can actually understand an undecided voter is if it's actually a strategic decision to entice the parties to give them more. An undecided voter is worth so much that Elon is literally giving away millions of dollars to sway them. Yeah it's chump change to him but it's still unprecedented. It would be kind of like a nullifying jurur, in that they're saying something completely different than what they're thinking. That totally gives undecided voters way more credit than they're actually due, because in reality they're just ignorant of the situation.
