Supergirl elects former Wonder Woman Lynda Carter as its fictional president

Carter’s casting has apparently been in the works for a long time, and though we don’t know how big her role will be in Supergirl’s second season, it does open the door for more fun with multiple universes. After all, The Flash introduced the concept of alternate realities (“Infinite Earths,” if you will) in its last season—which is how it justified the Supergirl crossover episode—and its recent season finale revealed that Shipp’s character was an alternate version of a different reality’s Flash, so President Lynda Carter could easily be a different reality’s Wonder Woman. Unless, she’s also really the Wonder Woman of the Supergirl universe, which is exactly the sort of fan-service treat that Berlanti’s shows have occasionally been known to pull off. (We’re assuming that the laws are different on Supergirl’s Earth, of course, otherwise a Themysciran like her wouldn’t be eligible for the presidency.)
