With no serious opposition left, the former Massachusetts governor easily won both contests. He won all 42 delegates at stake in Kentucky and at least 31 of the 33 delegates at stake in Arkansas.
Locally, Romney carried Jessamine County in the GOP primary election as he captured 1,222 votes.
Romney has 1,065 delegates, leaving him just 79 shy of the 1,144 delegates needed to win the GOP nomination for president. He should reach the threshold next week, when voters go to the polls in Texas, which offers 152 delegates.
Assured of the party nod, Romney has been in general-election mode for weeks. He's been spending much of his time fundraising and focusing on Democratic President Barack Obama.
As voters in the two Southern states weighed in, Romney spent Tuesday evening at a fundraising event in New York where his campaign said he raised $5 million. Romney's campaign has raised roughly $15 million during a three-day fundraising swing in the New York area.
Romney had struggled in some previous Southern contests, when former Pennsylvania Sen. Rick Santorum and former House Speaker Newt Gingrich were in the race. With them on the sidelines, Romney displayed solid support in two states he should win in November.
Even though they have left the race, Santorum, Gingrich and Texas Rep. Ron Paul were on the ballot in Kentucky and Arkansas.
President Barack Obama was unopposed in the Democratic primary, but “uncommitted” finished with a higher vote count, 644-580 in Jessamine County.
Barr to face Chandler in November
FRANKFORT — Republican Andy Barr has earned the right to a rematch against Democratic U.S. Rep. Ben Chandler in this fall's general election by besting his GOP opponents in Tuesday's 6th District primary.
Barr garnered 1,005 votes in Jessamine County, easily outdistancing his opponents, Patrick Kelly (107 votes) and Curtis Kenimer (57).
Barr lost a squeaker to Chandler two years ago and has been planning the sequel ever since.
In other fall congressional races, Republican incumbent Ed Whitfield will face Democrat Charles Hatchett in the 1st District. Republican incumbent Brett Guthrie will face Democrat David Lynn Williams in the 2nd.
Democratic incumbent John Yarmuth will face Republican Brooks Wicker in the 3rd. Republican nominee Thomas Massie will face Democrat Bill Adkins in the 4th. And Republican incumbent Hal Rogers will face Democrat Kenneth Stepp in the 5th.
