I sound just like a Democrat! I guess that makes me "bipartisan".
Open primary elections are a catastrophe for Republicans. There are always a bunch of Democrats and faux-Independents who crossover and "monkey-wrench" vote for the weakest possible Republican candidate.
Closed primary elections, where voters can only vote for candidates of the party in which the voter is registered, are a reasonable approach. That shuts out the "Independents" and is completely justified. If they want a voice in the selection of candidates, they should form their own parties and promote their own candidates.
Everybody gets to vote in the general election. Once. Dead people, imaginary people, non-citizens, and non-residents excluded of course. The Democrats will object to that last bit as "voter suppression". TFB for them.
>>”I sound just like a Democrat!”
No, not really. Caucuses don’t deny any registered party member the right to attend. But they do tend filter out, as you say, the less informed. Voting in a primary takes less effort than voting in a caucus. In the general election, voting should be as convenient as possible without sacrificing security. A part nomination is a different animal. Having a more well-informed subset of the party choosing the nominee is a very republican (small r) concept.
