On this, his 65th birthday, Mitt Romney has been looking for southern support -- as voters in Mississippi and Alabama prepare to make their choices in tomorrow's primaries.
He campaigned today alongside comedian Jeff Foxworthy -- known for his "you might be a redneck" jokes.
Some Republicans say it's essential for Romney to show strength in the South, which has become the party's most reliable region.
Rival Rick Santorum, meanwhile, has been campaigning in Mississippi -- and saying that his own path to the nomination depends on a divided GOP arriving at its nominating convention in late summer.
Romney is on pace to collect the 1,144 delegates he needs in June. The only hope for Santorum and Newt Gingrich is to keep Romney from achieving that number, and then forcing a fight at the convention in Tampa.
Santorum says his own standing will improve if conservatives unite behind him, and if Gingrich leaves the race soon.
