STORM LAKE, Iowa (AP) — As he scrambles to stop a slide in Iowa, Newt Gingrich’s strategy amounts to this: hammer home a message about jobs and the economy while wrapping himself in the mantle of Ronald Reagan. But the loquacious former House speaker keeps struggling to stay on message.

On a 22-stop bus tour of Iowa, Gingrich finds himself unloading on his GOP rivals and reviving talk of a Greek cruise that nearly sank his campaign earlier this year. He fields questions about his work for mortgage giant Freddie Mac, ethics allegations and whether his three marriages make him a polygamist. On Friday, he shed tears while discussing his late mother’s struggle with depression and mental illness.
