Fortunately since 2016 there are more closed primaries and primaries than caucus. I don’t think any state switched from closed to open or from primary to caucus.

Texas has an open primary, but, if there’s a runoff, you cannot switch then. The only person I personally know who switched parties to mess things up was a Democrat who thought it would be helpful to have Trump as the opponent.
