Romney Sees Christie as Potential G.O.P. Savior in "16 Mitt Romney said on Sunday that Gov. Chris Christie of New Jersey could be the Republican nominee for president in 2016 and could "save our party," comments that appeared to contradict reports that Mr. Romney's presidential campaign had been concerned about Mr. Christie's health. Appearing on NBC's "Meet the Press," Mr. Romney responded to questions about Mr. Christie's weight and whether it would be an obstacle to a presidential bid. He said Mr. Christie provided health records to his campaign last year while being considered as a potential vice-presidential running mate. "His health is very solid, very good," Mr. Romney said. Mr. Romney was not endorsing Mr. Christie, who is standing for re-election on Tuesday. He was addressing accounts in a coming book, "Double Down: Game Change 2012," about his vetting of Mr. Christie and other prospective running mates. The book contains anecdotes in which Mr. Romney purportedly made fun of Mr. Christie's girth, including the campaign's use of the code name "Pufferfish" to refer to the governor. One passage tells of Mr. Romney remarking about Mr. Christie's ability to pass through the narrow aisle of a campaign bus. Last week, Mr. Christie dismissed questions about the book, saying that its authors, Mark Halperin and John Heilemann, were just "trying to sell as many books as possible." Mr. Romney chose Representative Paul D. Ryan of Wisconsin as his running mate.
