WASHINGTON (AP) -- Former Massachusetts Gov. Mitt Romney padded his lead in the race for delegates Tuesday by winning Republican presidential primaries in Virginia, Massachusetts and Vermont.
Former Pennsylvania Sen. Rick Santorum added delegates by winning primaries in Tennessee and Oklahoma, while former House Speaker Newt Gingrich picked up delegates by winning Georgia.
Romney won at least 90 Super Tuesday delegates, Santorum won at least 34, Gingrich won at least 39 and Texas Rep. Ron Paul won at least six.
A total of 419 delegates were up for grabs in 10 states Tuesday. All the candidates were likely to add delegates as more votes were tallied.
In the overall race for delegates, Romney leads with 293, including endorsements from members of the Republican National Committee who automatically attend the convention and can support any candidate they choose. Santorum has 126 delegates, Gingrich has 72 and Paul has 31.
It takes 1,144 delegates to win the Republican nomination for president.
