Are you ready for it? What a Taylor Swift endorsement means for Kamala Harris.

I think OP's point is that they are important swing states.

That's exactly right. Top of funnel to bottom of funnel conversion.

I'm basing my metrics on what I've personally seen trying to get people to convert in fundraising for leftist political causes. Depending on the mission, messaging, we had some hits. But generally, less that one percent. Getting some one to give you their money isn't that different than asking them to sign up to vote. It's pretty onerous of they haven't done it before. You also have to hit them multiple times with the same message, from different sides, to get them to do something like show up in person.

I'm not able to say where I came up with the gratuitous 10%, but I'd like to pretend Taylor has ⭐ ✨ power over the Swifties. However, reality is you gotta stay on people with involvement and repeated messaging, reminders, deep engagement to keep them "activated". I'm not sure a one and done from Taylor does that. But I'd rather enjoy a nice fantasy that she's able to grow the electorate a smidge in a few key states. that's far more fun.
