Super Tuesday voters hit polling stations early

Eleven states across the country will hold contests awarding a combined 424 delegates. Here are the 11 contests, plus the delegates at stake in each: Alaska caucus (24), Georgia primary (76), Idaho caucus (32), Massachusetts primary (38), North Dakota caucus (28), Ohio primary (63), Oklahoma primary (40), Tennessee primary (55), Vermont primary (17), Virginia primary (46), and Wyoming caucus (5 of its 26 are elected tonight). The GOP presidential candidates have different strategies and strongholds in these 11 races. Romney hopes to lock down his home state of Massachusetts, Vermont, Virginia (where only he and Paul are on the ballot), and Idaho. Santorum is expecting wins in Oklahoma and Tennessee. Gingrich has focused on his home state of Georgia. And Paul has concentrated on the caucuses in Alaska, Idaho, and North Dakota, as well as the primary in Vermont.
