Who is the Flake Republican, helping Obama on his new Cuban opening?

“A descendant of Mormon pioneers who grew up in a family of 11 children on a cattle ranch in a small Arizona town, Snowflake (named for his ancestors), Mr. Flake, 52, is mild mannered and with a wry sense of humor. He admits he is an unlikely figure in the Cuba debate. “I took a poll of Cuban-Americans in Arizona,” he said, deadpan, “and both of them said, ‘Go ahead.’”

The Arizona senator has waged a long and lonely battle against fellow Republicans to push for easing restrictions on Cuba, and now the White House is counting on him.
