Jerry Brown to Christie: A Push-Up Wouldn't Kill Ya California governor hits back after Christie disses him as 'old retread' By Polly Davis Doig, Newser Staff Posted Sep 9, 2012 10:21 AM CDT 58 comments Comments New Jersey Governor Chris Christie walks onto the stage at the Republican National Convention in Tampa, Fla. on Tuesday, Aug. 28, 2012. (AP J. Scott Applewhite) (Newser) – Jerry Brown might be an "old retread" in Chris Christie's book, but he's a feisty old retread, thank you very much. The California governor today fired back at the New Jersey governor's criticism today on State of the Union, reports Politico. “Yes, well, I'm 74,” Brown said. “I'll be 74 1/2 next month. And but here I am. You know, there is some experience. Hopefully, there's some wisdom. So I got kind of warmed up and went on my speech and I said, OK, Christie, I challenge you to a three-mile race. Try some chin-ups maybe and some pushups.” Was he ever-so-subtly implying Christie is overweight, asked host Candy Crowley? “No, (it) essentially says this old retread can beat you any day of the week,” Brown responded.
