Lots of indies and even GOP switched to Dem just to vote in the primary. I almost did the same thing but I decided I didn’t want to be bugged by whoever won the primary for campaign money to the end of time.
As an addendum to #36 above, I think any pollster that uses raw voter registration percentages and equates them to self-declared party affiliation is going to be in for a nasty surprise come November.
Operation Chaos!
You could have switched for the primary and whoever won that primary would not have known unless you sent them money.
