His stump speeches were often centered on his ardent belief in federalism and championing states' rights. He talked about improving the country's intelligence efforts and securing the borders to bolster national security. He also talked about appointing conservative judges, which he felt was "the second most important thing a president could do."
Thompson also won the endorsement of anti-abortion group National Right to Life. The only GOP candidate to do so, Thompson put forth a Social Security plan, which he hoped would save the country from "bankrupting the next generation."
Before lunching on Southern delicacies in Columbia Saturday afternoon, as voters were going to the polls, Thompson told reporters that he was pleased by his campaign and proud of its efforts.
"We have been doing what we want to do, saying what we want to say, the way we wanna say it, being who we are. … It feels wonderful," Thompson said.
As for Thompson's future endeavors, Galen says he believes an endorsement is "not likely" at this time. He suspects the former candidate may hop back into radio commentary and spend time with his family.
"Fred Thompson has a lot of options available to him. Maybe since Sam Waterston has his job on 'Law & Order' as District Attorney, maybe Fred can get his job on Ameritrade commercials," Galen said.
