> It takes very little to swing an election if you're strategic, sometimes less than 1% of the vote

Good points. I'd add that the potential attackers include national intelligence agencies and other very well-resourced groups, including criminal organizations, corporations, and others. For them, the value of controlling the outcome of an election can be many billions of dollars or existential.

It doesn't matter if it takes a little or a lot; the cost is unlikely to be a deterrent to those types of attackers.
