Ten states are holding Super Tuesday primaries and caucuses to pick 419 delegates out of the 1,144 needed to clinch the Republican presidential nomination.
Here are delegate counts as of 5:55 a.m. ET on Wednesday, as tabulated by The Associated Press:
--Former Massachusetts Gov. Mitt Romney, 415 delegates.
--Former Sen. Rick Santorum of Pennsylvania, 176 delegates.
--Former House speaker Newt Gingrich, 105 delegates.
--Rep. Ron Paul of Texas, 47 delegates.
All told, the Super Tuesday states will send 437 delegates to the national convention beginning on Aug. 27 in Tampa, Fla. Some of them are superdelegates with automatic slots, who are not in play in Tuesday's elections. The AP count includes superdelegates who have already made their choices.
