With the shrinking field of GOP presidential candidates and the cancellation of the last scheduled Republican primary debate, the list of key events to watch out for is also growing smaller.

Of those, six states have more than 50 delegates at stake.
Here are some important events still to come in this turbulent nominating season.
Tuesday March 22: Headed to the Southwest
The next big primary comes in Arizona, where there are 58 delegates at stake in the winner-take-all state. Trump already has the backing of the state's infamous Maricopa County Sheriff Joe Arpaio, but be on the lookout for more trips there by candidates over the weekend and in early next week.
Utah, which has 40 delegates, has their primary on the same day.
Tuesday April 19: Empire State of Mind
A whole four weeks pass, with just one primary (Wisconsin, a winner-take-most state that could change to winner-take-all, with 42 delegates) during that time, until the next big contest. If a candidate is able to amasses a majority in both congressional districts and the statewide population vote, a winner-take-most state can morph into a winner-take-all state.
New York holds its primary April 19, and Donald Trump is surely hoping to win his home state. Even if he does, however, he likely won't be taking home the state's 95 delegates, who are not governed by winner-take-all rules.
Tuesday April 26: Another Mini-Super Tuesday?
There are five states holding their primaries at this time. Delaware with 16 delegates, is winner take all, while Maryland with 38 delegates and Pennsylvania with 71 delegates have potential to become winner take all.
This marks the last primary day with more than two states at a time for six weeks.
Tuesday June 7: Rush for Gold in California
There'll be a new rush in California before the state's primary because there are a whopping 172 delegates at stake.
The delegate-heavy state also differs from others because it is a winner-take-most state, which means that delegates can be allocated to the winner depending on district-level results, as well as their state-level performance.
Montana, New Jersey and South Dakota also have their winner-take-all primaries that day, along with New Mexico, which allocates its 24 delegates differently.
Monday July 18: The Final Say
The potentially historic convention starts in Cleveland more than a month after the party's last primary. Whether it is contested depends directly on the delegate counts, and whether one of the three remaining candidates has reached the magic 1,237 number.
If not, there's the prospect of four days of internal battling in the Buckeye State.
Editor’s Note: An earlier version of this story incorrectly reported that Wisconsin, Maryland, Pennsylvania, and New York were automatically winner-take all states; these could turn into winner-take-all states depending on the outcome. The story has also been updated with the U.S. territories still scheduled to have contests.
