FORT WORTH, Texas (Reuters) - New Jersey Governor Chris Christie endorsed Republican presidential front-runner Donald Trump on Friday, saying his former rival for the White House had the best chance at beating Democratic candidate Hillary Clinton in the Nov. 8 election. "The best person to beat Hillary Clinton in November on that stage last night is undoubtedly Donald Trump," Christie said at a news conference held ahead of a Trump campaign rally in Texas. "They do not know the playbook with Donald Trump because he is rewriting the playbook." (Reporting by Emily Stephenson and Susan Heavey; Editing by Mohammad Zargham)
