(CNN) -- Former Massachusetts Gov. Mitt Romney, already the presumptive Republican nominee, will win Tuesday's GOP presidential primaries in Kentucky and Arkansas, CNN projects.
With 119 of Kentucky's 120 counties reporting, Romney led with 67% of the vote, according to the website of the Kentucky State Board of Elections.
Texas Rep. Ron Paul had 13% of the vote, which was held roughly a week after he announced that he would no longer actively campaign for the GOP nod.
Former Sen. Rick Santorum of Pennsylvania, who suspended his White House bid in April, had 9%, while Newt Gingrich garnered 6% of the vote.
Forty-two delegates are at stake in the Kentucky race; 33 delegates are up for grabs in Arkansas.
With 58 of 75 counties reporting in Arkansas, Romney led the pack with 68% of the vote, according to the website of Arkansas Secretary of State Mark Martin.
Paul and Santorum followed, each with 13%. Gingrich had 5% of the tally.
According to a CNN estimate, Romney has 997 of the 1,144 delegates needed, with Santorum holding 264 delegates, Gingrich 145 and Paul 123. By CNN's count, the earliest Romney could reach the nomination threshold is late May, while President Barack Obama already has clinched the Democratic nomination, as expected.
The next primary vote is scheduled to take place in Texas on May 29.
