Republican Candidates Address Donald Trump and Volatility in Polls

Republican Candidates Address Donald Trump and Volatility in Polls  As the summer of Donald J. Trump winds down, some of the real estate mogul’s rivals took to the Sunday political talk shows, discussing plans for emerging from Mr. Trump’s shadow in the Republican field.

 Scott Walker The Wisconsin governor denied that his campaign has been forced to shift course by the potency of Mr. Trump’s candidacy.  “For us, I think the biggest spark for us is getting the message out that now’s not the time to put in place someone who hasn’t been tested before,” Mr. Walker told NBC’s “Meet the Press.”

Chris Christie As his own campaign struggles to take hold, the New Jersey governor told Fox News Sunday that he plans to be on the main stage for the second Republican debate Sept. 16 in Simi Valley, Calif., even though several polls show he no longer ranks in the top 10 of the Republican field.  Mr. Christie said he was not discouraged by recent polling, recalling how he was heavily outspent in his campaign for governor six years ago. “I’ve been an underdog for my entire political career,” he said.

 Bobby Jindal The Louisiana governor appeared on two programs, marking the 10th anniversary of Hurricane Katrina. He said the legacy of Katrina was proof that “American people love each other.”  “These last 10 years have shown the resilience of the American people,” Mr. Jindal told ABC’s “This Week.” He said his state was prepared for future hurricanes: “Our levies are stronger than they’ve ever been before, but we must not become complacent.”
