Mike Huckabee announced on Tuesday that he is running for president again. Mr. Huckabee isboth a Baptist preacher and a former governor of the state of Arkansas.

Ford O'Connell is a Republican strategist.
"I think when all is said and done and we get to the general election in 2016, you're going tohave three issues: economic mobility, jobs and national security. And while they do overlap,the ability for Republicans to distinguish themselves with the Republican primary on nationalsecurity is going to be very, very important."

He is the sonand brother of two former U.S. presidents. Behind Mr. Bush in the polls is Wisconsin GovernorScott Walker. He is popular with Republicans for opposing labor unions.
