Former Massachusetts Gov. Mitt Romney added to his lead in the race for delegates Tuesday by winning the Republican presidential primary in Illinois.
Romney won at least 41 delegates in Illinois and former Pennsylvania Sen. Rick Santorum won at least 10. The two rivals were battling for the last three delegates at stake in the primary, but the results were too close to call on election night.
Former House Speaker Newt Gingrich and Texas Rep. Ron Paul were shut out.
Romney leads the overall race for delegates with 563, while Santorum has 263, Gingrich 135 and Paul 50.
A total of 1,144 delegates are needed to win the Republican nomination.
So far, Romney has won 54 percent of the delegates at stake in primaries and caucuses. That puts him on pace to clinch the nomination in June, but without much room for error.
Santorum has won 27 percent of the primary and caucus delegates at stake so far. He would need to win 74 percent of the remaining delegates to clinch the nomination before the party's national convention in August.
