I assume “swing voters” are just balancing positions where both parties offer (or threaten) something or other that is dear to them. For example, people who wanted an improved economy under Trump but may have also wanted affirmative action jobs may have been in a real bind recently.
I think there are some that can rationally articulate why they might vote for a dem, then a pub, then a dem and so on. I also think many can’t, or their explanation isn’t rational. There is a reason why someone who is adjudged by the media to have won a debate rise in actual polls afterwards. If you have a guiding political philosophy, why would you change your mind based on debate skill?
We haven’t even had 65% eligible voter turnout in presidential since 1908. Off year congessional elections average around 40%, way less for local elections. Most of the time the national popular vote is won by less than 5%. All campaign money is meant to sway the swayable into voting one way or another or even to vote or not vote at all. And supposedly the swayable decide elections.
