The supposed logic behind the switch to the top-two primary was to get all candidates to run their campaigns, from the start, directed at everyone in the district across the political spectrum, instead of first catering to the small group of primary voters in each party. So, the candidates are basically already running what we would consider big, expensive, general-election-style campaigns for the “primary,” and they will need to sustain this big, general-election-style campaign for the months until the runoff election.
