However, his personal life has often crept into his public life as evidenced by a much publicised incident at the National Rifle Association. In the middle of making a speech at the recent conference, Giuliani answered a call from his wife on his cell phone. He told her where he was and expressed his love for her.
"Quite honestly since September 11 most of the time when we get on a plane we talk to each other and just reaffirm the fact that we love each other," Giuliani explained. "Sometimes if I'm in the middle of a very, very sensitive meeting, I don't take the call right then. I wait. But I thought it would be kind of nice if I took it at that point, and I'd done that before in engagements, and I didn't realise it would create any kind of controversy."
While the series of CBN interviews portrays Giuliani in a somewhat redemptive light, with Brody calling his family response "heartfelt", one critic was quick to point out the irony in Giuliani's explanations.
"It's interesting that Giuliani makes this reaffirmation with his third wife before air travel 'since September 11', given that on September 11, Giuliani was married to someone else," wrote Steve Benen on his blog The Carpet Bagger Report.
Benen also pointed out that Jesus didn't "put the stones down" since he never picked the stones up.
While nearly all Americans would agree that faith is playing a prominent role in the current presidential race, evangelical leaders have contended that Christians should be more concerned about where the candidates stand on issues, than the amount of "God Talk" from each presidential hopeful.
"I appreciate that the candidates are taking a risk when they talk about their faith," said Prison Fellowship Ministries President Mark Earley in a commentary last month.
"The problem is that all of this 'God Talk' misses the point: what Christians want - or should want - is a candidate who shares their moral and culture concerns, not just their religious vocabulary."
In addition to his divorces, Giuliani has created distance between many conservative Christians and himself with his support of abortion and gay rights.
Despite criticism, Giuliani currently leads the race for the 2008 GOP nomination, followed closely by actor and former senator Fred Thompson, who joined the race near the start of this month.
Republican delegates will elect the GOP candidate at the Republican National Convention to be held in Minneapolis/St Paul, Minnesota, on September 1-4, 2008.
