Alex Salkever AlexSalkever @nireyal @Kantrowitz I think there are some very useful forms of self-reporting. The type / details of the study matter. If it is, say, pulse studies where they are asked multiple times per day, those tend to be a lot more valid. Also, if they are longitudinal. I don't know the details of these.

Alex Salkever AlexSalkever @jennycohn1: The voter data sought by PA’s GOP is exactly the type of data that, in many states (I don’t know about PA), wld give the GOP enough info to rig an election by submitting address changes, deleting voter registrations, or requesting absentee ballots.

Alex Salkever AlexSalkever @busblog I like it. You want to do a recall, assume the risk. Just like in court. It's way too easy to do a recall in California - regardless of party.
