WASHINGTON (AP) -- Former Massachusetts Gov. Mitt Romney padded his lead in the race for delegates Tuesday by winning Republican presidential contests in at least four states.
Former Pennsylvania Sen. Rick Santorum added delegates by winning contests in at least three states, while former House Speaker Newt Gingrich won the primary in Georgia, the state he used to represent in Congress.
Romney won at least 148 Super Tuesday delegates and Santorum won at least 64. Gingrich won at least 52 delegates and Texas Rep. Ron Paul got at least 14.
So far, Romney is winning 53 percent of the Super Tuesday delegates; Santorum is winning 23 percent.
A total of 419 delegates were up for grabs in 10 states Tuesday. Most of the candidates were likely to add delegates as more votes were tallied.
In the overall race for convention delegates, Romney leads with 351, including endorsements from members of the Republican National Committee who automatically attend the convention and can support any candidate they choose. Santorum has 156 delegates, Gingrich has 85 and Paul has 39.
It will take 1,144 delegates at the party's national convention this summer to win the Republican nomination for president.
