The CAH folks have pretty good lawyers. Judging purely on the fact that they formed a Super PAC, they likely have good legal cover.

I found this pretty interesting:

How do you know who didn’t vote? We formed a Super PAC and bought the personal voting records of every American citizen from a data broker we found on the internet. It’s pretty fucked up.

And later on:

How do you know who’s “blue leaning”? We got your partisan lean from the same data broker who sold us your voting history. You wouldn’t believe how easy it was for us to get this stuff. So fucked up!

If they are basing this on which primary you vote in, it's going to be terrible since people like me who live in a swing state vote in the Republican primary since that's a more effective use of my vote than the Democratic primary.
