Mitt Romney won Republican presidential primaries in five states on Tuesday, adding to a delegate total that already exceeds the number needed to win the nomination.
Romney won primaries in California, New Jersey, South Dakota, New Mexico and Montana.
Romney has 1,398 delegates. He needs 1,144 to win the Republican nomination at the party’s national convention in August.
A total of 264 delegates were at stake in Tuesday’s contests including 169 in California and Romney has a chance to win them all.
With the primary season winding down, Romney is already in general election mode. He will take on Democrat Barack Obama in the fall. After Tuesday, only one Republican presidential primary remains, in Utah on June 26.
