If there is a stand-out among these stand-outs, it is probably Julianne Hough as Dusty, whom we first see vomiting blue slushies in the White House bathroom, because she's pregnant...with the president's baby. If Dusty appears to be a stereotypical bimbo, no more capable of having a coherent thought than the flax she grows on a farm in Iowa, little by little we learn that she's extraordinary in a whole host of ways, some of which (but far from all of which) are X-rated. (She's where the ass play comes into play, and that's all I'll say.) Hough, who among her other accomplishments was a two-time champion of 'Dancing with the Stars,' does triple duty in 'POTUS' - at one point, rapping while she plays her body like a drum; at another, leading the rest of the ladies in two different song and dance numbers, which are in the play because....well, why not. Besides, Susan Stroman, four-time Tony winner for choreography (and once for direction), is the director, so why not give her something to do besides stage these characters standing around spouting vulgarities in the different elegant rooms of the White House that spin around on designer Beowulf Boritt's turntable set.
