5. Jimmy Fallon
The Tonight Show host's impression is the tidiest. As you'll see above, the vocal ticks, gestures, catchphrases, lips, postures, glances, tempos, and costumes are pitch perfect. Fallon, however, can often err on the side of adopting too much goofiness, making him seem more like a jester than a politician.
Trumpiest line: "Thank me. We're gonna win big, we're gonna win big. Thank me."
