This isn’t a political ad, and anyway, the audience is already sold. How could it not be? With no live foils onstage — another unavoidable condition of the genre — Taylor works the room relentlessly. Every laugh is procured and brought home like pork. And while she is a fine enough actress to integrate that kind of wolfishness into her characterization, you can’t help thinking it would be nice if she could press some actual onstage, co-star flesh. After all, it’s not just a good line and good politics, but good playwriting advice as well, when Taylor has Richards say, near the end, “Why should your life be just about you?”
