I have come to genuinely love these two.
First time in my life for this sort of feeling about candidates. Look at this adorable picture. Jill Biden is smooching Barack, and Joe Biden is hugging Michelle in a totally affectionate, admiring, non-gross way. And she's taller than him!
This sort of thing makes me really happy.
Addendum to the above: I just noticed that Joe Biden has very manly forearms. With his shirtsleeves rolled up, he looks kind of hot.
