To be quite clear, I wasn't using those numbers to make the point that a Democrat will have a sure win. Given the Republican Party and their tactics, that's not even remotely close to a certainty. Rather, the better takeaway from that is that the difference in electability between the Top Democratic Party contenders is... small.
Of course! And, quite frankly, it's well known that Democrat-leaning folk are less likely to vote, overall, before getting to the redshift in Republican-controlled states that fairly certainly results from lots of Democratic Party-leaning voters getting purged from the voting rolls without their knowledge.
Why would that be curious? It's not remotely new news and had little to do with the point made, though thank you for making additional points.
Not really what I said. To put it a bit differently, I said that picking a candidate "just" because of the perception that they're the most electable is an increasingly poor reason. That doesn't remove it from consideration completely, just pulls it off the pedestal that it's been put on.
And seniors, of course, are likely the most likely to actually vote group.
Increasingly so, yes.
