I had the same exact phenomenon happen to me with a man named Barack Obama.
I honestly believe that having a crush on another person is more than just physical appearance. I don't know how to describe it but it's a feeling of rapport or some sort of connection. The man oozes class, intelligence and vibrancy from every smile to every word he speaks.
And I know that there have been other DU'ers that feel the same way, along with female celebrities about Barack Obama, so it's just not me.
If I would have happen to run across him post presidency (during the TSF years) Michelle or the SS would have to pull me off him from a way too long hug. I wouldn't have voluntarily let go from an embrace from this man.
There's something special about Kamala Harris as well. There's a rapport there with folks who see it and understand it. She's a beautiful lady but it's not just about being beautiful on the outside with her, she's beautiful on the inside. She relates with people and logical people can feel it.
I absolutely get it.
