Kind of missing the point. Call time is about "access" to the candidate. Most large campaigns already have call center operations for low-dollar donors. Donors that max out do so because they have the candidate's attention for a period of time. Not possible to automate (and automating it would defeat the purpose).
Ah thanks for the correction! I misunderstood the article's description of "call time" as a synonym for "call bank", as it consists of volunteers calling and asking for donations. I can see how automation is not feasible with this definition.
