Oh, I don’t actually think it’s necessarily a bad thing.
It kind of eliminates the purpose of political parties at all though. Of course, from my personal perspective, this isn’t really a bad thing.
Yes, but you are guaranteed one candidate from every party in that final election. The final election is between the parties. The open primary top two thing makes it between two candidates that can be from the same party.
Again, I’m not saying this is necessarily bad.
However, there is one potential case where it can break down, and i seem to recall this almost happening in California in a few districts.
Imagine a case where a district is strongly Democratic, say, plus 10 for the Democrats.
In that district, Democratic candidates (especially without an incumbent) would likely think that they have a good shot at the seat. So you get a bunch of folks in the primary. Say, 15 different candidates.
The Republicans, being weaker, only field 2 guys. Maybe neither is really great, no name guys.
In that situation, you can run into a case where the 45% of the primary vote from Republicans gets split across two guys, say giving them 20 and 25% respectively.
The 55% of the vote that’s Democratic gets split across 15 candidates. The total of these is much more than either Republican, but none of them get over 20%.
The end result is that you end up with a solidly Democratic district, where there are only republicans in the general election.
