From the article:
"Gus Curry as Jackson has a strong, soaring voice and a strong falsetto which he shows off in the number "Rock Star." In "Jackson," the president is often portrayed as someone with the mannerisms of a petulant teenager ("Tariff? Blah!" he exclaims at one point), but Curry strikes a good balance between the humor of the character and showing near the end of the show the true desperation of Jackson, who has found that his strategy of representing the populace as its leader hasn't gone like he thought it would."
