It should be up to the parties to decide whether they would prefer a relatively high-turnout delegate selection scheme that would put more influence with mass electorates or a system that empowers smaller, more dedicated groups of party activists. The parties are also best positioned to figure out which influences they prefer (including second-order influences; mass electorates give more power to the media, which parties might not like). More to the point, it’s the parties who have everything at stake here, so they should be the ones to choose.
