Final answer:
The actual problems with California's "top-two" primary system include the prohibition of "write-in" votes in the general election and may not necessarily represent all issues perceived by the public or mentioned in the question. The system does not allow for party replacement of candidates between the June primary and the November election, nor does it include June primary votes in the November election outcome.
Step-by-step explanation:
Problems with California's "top-two" primary system include the following: first, no "write-in" votes are allowed on the November ballot, which limits voter choice and may exclude popular candidates who did not appear on the primary ballot.
Second, contrary to the student's suggestion, parties do not replace the candidate who won the June primary with a new candidate for the November general election; the top two vote-getters in the June primary move forward to the general election, even if they are from the same party.
Third, the system allows all voters to vote in the November election regardless of whether they voted in the June primary election, meaning the suggestion that only June voters can vote in November is incorrect.
Lastly, in the general election, the candidate with the most votes wins; there is no addition of votes from the June primary to the November total, so the concern that the candidate with the fewest votes in November could win due to June primary votes is unfounded.
