JEFFERSON CITY, Mo. (AP) — Former Pennsylvania Sen. Rick Santorum won Missouri's nonbinding Republican presidential primary Tuesday, claiming momentum in his challenge against national frontrunner Mitt Romney even though the victory won't earn him any delegates.

Santorum was the only Republican candidate to campaign for Missouri's primary. He had expressed hope that it could help cement him as a conservative alternative to Romney heading into a big round of state primaries in early March.

Missouri's primary was essentially a glorified public opinion poll. That's because state Republicans chose to award their delegates to the Republican National Convention using a caucus system that will begin in mid-March.
