The Latest on the Kentucky primary election in which voters are casting ballots on a slate of local, state and federal races including the Democratic presidential primary.

Hillary Clinton is declaring victory in Kentucky's presidential primary, but her race with Bernie Sanders still remains too close to call.
Clinton says in a statement posted on Twitter that she just won the state's primary and thanks "everyone who turned out." She says, "We're always stronger united."
With nearly all the votes counted, Clinton holds a narrow lead of less than one-half of 1 percent of the vote.
The Sanders campaign is not immediately saying whether it will challenge the results. Kentucky does not have an automatic recount.
Clinton holds a commanding lead of nearly 300 pledged delegates over Sanders and a dominant advantage among party officials and elected leaders known as superdelegates. The outcomes in Tuesday's primaries in Kentucky and Oregon are not expected to change the arc of the Democratic race.
10:45 p.m.
Just 118 short of the delegates needed to win the Democratic presidential nomination, Hillary Clinton remains on track to do so by early June.
Clinton and Sanders each picked up at least 25 delegates Tuesday in Kentucky's presidential primary.
The margin in Kentucky between the two is less than one-half of 1 percent, which means the race is too close to call.
After the votes in Oregon are counted later Tuesday, the next caucuses are in the Virgin Islands on June 4 and Puerto Rico on June 5, with a combined total of 67 delegates at stake.
If Sanders still hopes to reach the 2,383 needed to win, he would have to pick up an overwhelming 88 percent of the remaining delegates and uncommitted superdelegates.
That's all but impossible under the Democrats' system of awarding delegates in proportion to the vote, rather than winner-takes-all.
Democratic presidential primary in Kentucky between Hillary Clinton and Bernie Sanders is too close to call.

Democratic U.S. Senate nominee Jim Gray came out swinging in his uphill fight against Republican Sen. Rand Paul, aiming to land some early shots to undermine the incumbent's advantages in GOP-trending Kentucky.
Claiming victory Tuesday night over six underfunded Democrats in the primary, the Lexington mayor and wealthy businessman described Paul as "big on talk and little on action."
Paul easily defeated his two Republican challengers, James Gould and Steve Slaughter, taking a successful first step in putting his failed presidential campaign behind him.
He says telling people he didn't do his job is a difficult sell, pointing to a 96 percent attendance record for Senate votes. He also says he helped sponsor more than 100 bills and offered more than 300 amendments to bills during his term.

James Comer has won the Republican nomination in Kentucky's 1st Congressional District one year after a heartbreakingly close loss in the GOP primary for governor.
Comer wants to replace retiring U.S. Rep. Ed Whitfield, who has held the seat since 1995. He defeated Michael Pape, Whitfield's district director for two decades, and Hickman County Attorney Jason Batts. Miles A. Caughey Jr. finished fourth.
After losing the nomination for governor by just 83 votes last year, Comer said he planned to return to his farm in Tompkinsville. But when Whitfield announced his retirement, it was an opportunity for Comer to capitalize on his immense popularity in the 1st District.
Comer will face Democrat Sam Gaskins in the November election.

Democrats Hillary Clinton and Bernie Sanders are in a closely divided race in Kentucky's presidential primary as the results are reported Tuesday night.
Clinton is trying to avoid losses in Kentucky and Oregon to blunt Sanders' recent momentum. Clinton holds a formidable lead of nearly 300 pledged delegates but Sanders has won primaries in Indiana and West Virginia as the primary race approaches the final contests in June.
Clinton is on track to clinch the Democratic nomination in early June but she's trying to avoid primary defeats during the final stretch as she prepares for Republican Donald Trump.
Sanders is favored in Oregon's primary on Tuesday night.
7:15 p.m.
Lexington Mayor Jim Gray has won the Democratic U.S. Senate nomination in Kentucky to set up a fall campaign against Republican Sen. Rand Paul.
Gray promoted his city hall and business experience in his campaign against six underfunded Democratic opponents in Tuesday's primary.
Gray is running as an openly gay candidate in a state where Rowan County Clerk Kim Davis drew widespread attention last year for her opposition to same-sex marriage.
The Democrat helped build his family's successful construction company, and he dipped into his personal wealth to make a $1 million loan to his campaign.
Kentucky Democrats last won a U.S. Senate election in 1992.

U.S. Sen. Rand Paul has won the Republican nomination in his pursuit of a second term.
Paul juggled dual campaigns for the White House and re-election to the Senate until early this year, when he ended his struggling presidential bid. In Tuesday's primary election, the Kentucky Republican defeated his two Republican challengers — James Gould and Steve Slaughter.
Paul rode a wave of tea party support in winning his Senate seat in 2010. The libertarian-leaning Paul kept to his low tax-and-spend mantra during his first Senate term. He also championed efforts to curtail the federal government's surveillance powers, and has ventured into minority neighborhoods to advocate for criminal-justice reforms.
6:55 p.m.
The Rev. Nancy Jo Kemper, a longtime lobbyist on social justice issues in Frankfort, has won the 6th District Democratic primary and will face incumbent U.S. Rep. Andy Barr in November.
Kemper defeated Geoff Young, a retired state energy official who had previously lost bids for governor, state representative and Congress. She has criticized Barr, a two-term incumbent who won in a landslide two years ago, as being too cozy with big banks.
The 74-year-old Kemper is pastor of New Union Christian Church, a Disciples of Christ congregation in Woodford County.
Young also criticized Barr but also took on the Democratic Party establishment, calling it "dumber than a bucket of rocks" in one campaign ad.

U.S. Rep. Andy Barr has fended off a tea party challenge in the Republican primary in the 6th Congressional District and won the right to defend his seat in November.
Barr, a Lexington lawyer seeking his third term in Congress, easily defeated Harrison County tea party activist Roger Brill for the GOP nomination on Tuesday.
He'll face the Rev. Nancy Jo Kemper or retired state energy official Geoff Young, who are vying for the Democratic nomination in the central Kentucky district.
Barr, a member of the House Financial Services Committee, has worked to roll back sections of the Dodd-Frank Wall Street reform and Consumer Protection Act during his time in Congress. Both Democrats have accused him of being too cozy with big banks.

Republican U.S. Rep. Hal Rogers breezed to re-election Tuesday, clinching a record 19th term in office.
The Somerset lawyer has served in Congress since 1981, making him the longest-serving Kentucky Republican ever elected to federal office.
He represents Kentucky's 5th District, the Appalachian eastern part of the state the remains one of the poorest congressional districts in America.
He is chairman of the powerful House Appropriations Committee, which oversees federal government spending. He and former Democratic Gov. Steve Beshear launched Shaping Our Appalachian Region, an effort to transform eastern Kentucky's economy after the decline of the coal industry.
Rogers handily beat Republican John Burk Jr. in Tuesday's primary and does not have a Democratic challenger for the November election.
