Jeff Flake, R-Ariz, center, arrives at a Havana, Cuba, hotel, one in a delegation of U.S. lawmakers following leadership shifts there, and possibilities for change in U.S. policies towards the Island. In Flake's re-election race both a GOP primary opponent and Democrats are the six-term congressman as a Washington insider, because he worked as a lobbyist 20 years ago for a Namibian uranium operation with ties to Iran. Flake says he's long opposed unilateral penalties like sanctions, whether against Iran, Sudan, Cuba, Myanmar or any country, because he saw the damage sanctions can have on innocent people during his time in Nambia.
