Donald Trump might be the presumptive GOP nominee [1] and Hillary Clinton might have the Democratic upper hand, but voters are still casting ballots in two states today. Check out everything you need to know about the Kentucky Democratic primary and the Oregon primary.

Here's what's happening:

• Hillary Clinton is the apparent winner [2] of the Kentucky Democratic primary, although the Associated Press says the race is still too close [3] to call. Numbers show [4] Clinton with 46.8 percent of the vote, while Bernie Sanders has 46.3 percent.
• Clinton tweeted out a message declaring victory:

We just won Kentucky! Thanks to everyone who turned out. We're always stronger united. https://t.co/8qYPHIje8I [5] pic.twitter.com/elNUP4nFoO [6]

• But the Sanders campaign saw it differently, with campaign manager Jeff Weaver telling NBC [8] it was "essentially a tie in a state they [Clinton] dominated last time."
• It's no shocker that Trump won the Oregon GOP primary since he is the only Republican candidate left [9] in the race. Sanders took the Democratic race there with 53 percent of the vote.
• Going into Tuesday, Clinton had 1,716 delegates and Sanders had 1,433 out of the 2,383 needed. (This count does not include superdelegates [10], many of whom have pledged to vote for Clinton but can still change their minds.)
• Fifty-five Democratic delegates are up for grabs in Kentucky, with 61 in Oregon.
• Trump has amassed 1,086 delegates delegates out of the 1,237 necessary to win the party nomination.

Here's what it means:

• The tight Kentucky race doesn't help unify the Democratic party, especially after this weekend's dramatic Democratic Nevada convention [11]. Sanders supporters believe he was blocked from getting the number of delegates he deserves and have been harassing Nevada Democratic Chairwoman Roberta Lange with nasty texts and voicemails.
• With this Oregon victory, Sanders continues to prove how significant he has been during this election [12], despite the mathematical signs that his campaign is virtually over [13].
• You can plan to see both sides gear up for a Trump vs. Clinton showdown [14] — Trump is already working on an attack against Clinton's character [15], while she is anticipating his vague one-liners [16].

Here's what's next:

• There will be a Republican primary in Washington state on Tuesday, May 24, but the next major battles come on June 7 with California, Montana, New Jersey, New Mexico, and South Dakota hosting primaries for both parties. North Dakota will also hold its Democratic primary the same day.
