Rick Santorum wins MS, AL GOP primaries

WASHINGTON (AP) - Rick Santorum has won Mississippi's Republican presidential primary - completing a two-state sweep of Deep South contests.

Santorum narrowly edged rivals Newt Gingrich and Mitt Romney to win Mississippi. Earlier, Santorum won Alabama's GOP primary with a slightly wider margin.

Evangelicals played a key role in both states. Nearly 4 of 5 voters surveyed in exit polls called themselves born-again or evangelical.
