Bernie Sanders won the the Democratic presidential primary in Oregon Tuesday night, while the race in Kentucky appeared to be too close to call, the Associated Press reports.
The margin between the two candidates was less than 1 percent in Kentucky, with Hillary Clinton leading ever so slightly.
Meanwhile, Clinton declared victory in the Kentucky primary on Twitter, thanking "everyone who turned out."
Clinton and competitor Bernie Sanders will more or less split the delegates available in the state -- a victory for Clinton, who pushes even closer to securing her party's nomination.
At a California rally Tuesday night, Sanders said it appears he will end up with about "half of the delegates" in Kentucky.
The results come as time is quickly running out for Sanders to make a final push for the nomination, as Clinton inches ever closer to victory. In three straight weeks, the Vermont senator has picked up state wins, but each have failed to put a dent in Clinton’s significant lead.
Voters on Tuesday evening were also scheduled to vote in Oregon on the Republican side, in which Trump is the presumptive nominee.
After the Democratic results, Clinton held at least 1,765 delegates in total, not including superdelegates, while Sanders had at least 1,526. With superdelegates included, Clinton boasts an impressive 2,289 -- more than 95 percent of what's needed to secure her party's nomination.
A total of 2,383 delegates are needed to become the Democratic nominee.
The next Democratic primaries will be held on June 7, when North Dakota, California, Montana, New Jersey, New Mexico and South Dakota are scheduled to vote.
