Rudy Giuliani is racking up the endorsement of Jeb Bush, Jr. whose relevance to political office, as best I can tell, is that he's Jeb Bush's son, George W. Bush's nephew, and George H.W. Bush's grandson. This has been commented on previously in light of the staggering fact that we're apparently going to go Bush-Clinton-Bush-Clinton in terms of the White House, but there's really something astounding about the dynastification of American politics.
