Editor's note: New Yorkers have just under two hours remaining to cast their ballots in the state's presidential primary, which is considered to be competitive for the first time in decades. GOP frontunner Donald Trump and Democrat Hillary Clinton are widely considered to win their respective primaries. But the day hasn't been without controversy; more than 125,000 Democratic voters in Brooklyn, NY, were purged from the borough's voting rolls, and city comptroller Scott Stringer has promised an audit of the city's elections board. Statewide, the attorney general's office said its voter hotline received 562 calls and 140 emails from voters as of 5 p.m. ET. And, around 4:30 p.m. ET, a federal judge denied a temporary restraining order request to open New York's closed primaries to all voters, regardless of party affiliation. The polls close at 9 p.m. ET, and we'll have coverage of returns on our app. - Rebecca

Brooklyn (/ˈbrʊklᵻn/) is the most populous of New York City's five boroughs, with a Census-estimated 2,636,735 residents in 2015. It is geographically adjacent to the borough of Queens at the southwestern end of Long Island. Since 1896, Brooklyn has had the same boundaries as Kings County, the most populous county in New York state and the second-most densely populated county in the United States, after the county of New York (which is coextensive with the borough of Manhattan).
With a land area of 71 square miles (180 km2) and water area of 26 square miles (67 km2), Kings County is New York state's fourth-smallest county by land area and third-smallest by total area, though it is the second-largest among the city's five boroughs. Today, if it were an independent city, Brooklyn would rank as the fourth most populous city in the U.S., behind only the other boroughs of New York City combined, Los Angeles, and Chicago.
Brooklyn was an independent incorporated city (and previously an authorized village and town within the provisions of the New York State Constitution), until January 1, 1898, when, after a long political campaign and public relations battle during the 1890s, according to the new Municipal Charter of "Greater New York," Brooklyn was consolidated with the other cities, boroughs, and counties to form the modern "City of New York" surrounding the Upper New York Bay with five constituent boroughs. The borough continues, however, to maintain a distinct culture. Many Brooklyn neighborhoods are ethnic enclaves. Brooklyn's official motto, displayed on the Borough seal and flag, is Eendraght Maeckt Maght, which translates from early modern Dutch to "Unity makes strength".
In the first decades of the 21st century, Brooklyn has experienced a renaissance as an avant garde destination, with concomitant gentrification, dramatic house price increases, and a decrease in housing affordability. Since 2010, Brooklyn has evolved into a thriving hub of entrepreneurship and high technology startup firms.
