THE REPUBLICAN PRESIDENTIAL CONTENDERS: From left, former Arkansas Gov. Mike Huckabee, former Sen. Fred Thompson of Tennessee, former Massachusetts Gov. Mitt Romney, former New York City Mayor Rudy Giuliani, Rep. Ron Paul of Texas, Sen. John McCain of Arizona and Rep. Duncan Hunter of California. Mr. Thompson, a former actor on Law & Order, made headlines with his late but much-anticipated entry into the race. Mr. Romney and Mr. Huckabee both brought religion to the forefront later in the year; Mr. Romney delivered a speech to address his Mormon faith and Mr. Huckabee, a preacher, forged ahead on Christian values.
