Here, anomalous viscous fluid dynamics model calculations for ${}_{44}^{96}{Ru} + {}_{44}^{96}{Ru}$ and ${}_{40}^{96}{Zr} + {}_{40}^{96}{Zr}$ collisions ( $\sqrt{s_{N N}} = 200$ GeV) are used in concert with a charge-sensitive correlator to test its ability to detect and characterize the charge separation difference expected from the chiral magnetic effect (CME) in these isobaric collisions. The tests indicate a larger charge separation for ${}_{44}^{96}{Ru} + {}_{44}^{96}{Ru}$ than for ${}_{40}^{96}{Zr} + {}_{40}^{96}{Zr}$ collisions and a discernible CME-driven difference of $~ 10 %$ in the presence of realistic non-CME backgrounds. Furthermore, they suggest a strategy for evaluating the relative influence of the background correlations, present for each isobar. These results suggest that charge-separation measurements for these isobaric species could serve to further constrain unambiguous identification and characterization of the CME in upcoming measurements at the Relativistic Heavy Ion Collider
