BILOXI, Miss. (AP) — Rick Santorum said Monday his path to the Republican Party's presidential nomination counts on continued chaos in the field and a fractured GOP arriving at its nominating convention in late summer. Though former Massachusetts Gov. Mitt Romney has a commanding lead in the crucial race for delegates to the national convention, Santorum told reporters a day before Alabama and Mississippi's presidential primaries that his standing in the race will improve if conservatives coalesce behind him — and if Newt Gingrich exits the race soon.
