(CNN) - When Gov. Rick Perry of Texas called for a day of prayer and fasting in Houston, world-famous televangelist John Hagee answered enthusiastically.

"We pray for our governor, Rick Perry," he gruffly proclaimed, "who has had the courage today to call this time of fasting and prayer just as Abraham Lincoln did in the darkest days of the Civil War."

When Perry officially launches his presidential campaign this weekend, he will not be the only Republican candidate to carry the banner of Christian piety. The presidential pre-primary season has not featured so many brave Christian Abraham Lincolns since the days of Abraham Lincoln himself.
