"George W. Bush and puppet master Dick Cheney,"2004 by David Levine (website) from a show at the Forum Gallery.
See a slideshow of other portraits at the November Vanity Fair, which also includes an article, “Levine in Winter,” by David Margolick, about Levine's work and his disappearance from The New York Review of Books due to macular degeneration. (Hat tip to Elaine Fleck for letting me know about the article.)
An archive of Levine's work at the Review is here. On Election Day, November 4 Fantagraphics will publish American Presidents, a collection of artist David Levine’s commander-in-chief caricatures with a foreword by Bill Moyers.
