Fred Thompson campaigned outside of Atlanta Thursday as his wife, Jeri, looked on.
KENNESAW, Georgia (CNN) - Sharpening his rhetoric against Republican opponents Rudy Giuliani and Mitt Romney, presidential contender Fred Thompson said Thursday he had a long-standing conservative record before challengers were "talking the talk."
Thompson spoke to reporters as he picked up endorsements from three elected county officials in Georgia's Cobb County - a heavily Republican area in the northern Atlanta suburbs. Underscoring the theme of the trip, Thompson was introduced as "the only conservative who can beat Hillary Clinton."
The former Tennessee senator blasted rivals for previous stands on abortion and immigration, telling the crowd in an airport hanger, "I was walking the walk" on conservative issues while others weren't even talking the
Thompson said that while in the Senate he had opposed cities that declared themselves sanctuaries for illegal immigrants at the same time, he said, Giuliani allowed that action as mayor of New York City.
Romney has tried to make an issue of Giuliani's position, but Thompson said the former Massachusetts governor "didn't say anything about sanctuary cities until recently."
Appealing for conservative support, he told the gathering he had a 100 percent record opposing abortion rights, saying of his rivals, "I'll ask anybody to compare their record with mine in terms of where they were yesterday, where they are today, and more importantly, where they'll be tomorrow. You can look and see where a fellow is liable to go in the future based on where he's been in the past."
Thompson is in Atlanta raising money at several private afternoon events.
