Santorum on Defensive Over a Remark.

WEST MONROE, La. -- Rick Santorum on Friday recalibrated a remark he made a day earlier suggesting that the United States would be just as well off re-electing President Obama as it would be electing Mitt Romney in November. Speaking to a crowd of several hundred people at a shooting range in northern Louisiana, Mr. Santorum made a point of saying Friday morning that he would back whoever is the Republican presidential nominee in the fall.
