Fred Thompson on Wednesday defended his support for limits on campaign contributions - a sore point among many fellow Republicans - and said rival Mitt Romney had reversed his view on the issue.
At an eastern Iowa campaign event, a man in the audience said he liked the former Tennessee senator's conservative thinking on most issues but questioned his support for the McCain-Feingold Act. The campaign finance overhaul, which became law in 2002, caps contributions and is disliked by many in the GOP.
"A lot of my Republican colleagues still have a hard time with it - they don't understand it and I appreciate that. But standing up, putting the government in the right place to do its job, to do things as best we can to minimize the temptation and the opportunity for corruption ... is still a valid, solid, conservative concept that I stand for," Thompson said.
