New York’s liberal mayor, Bill de Blasio, wants Democrats to stage their 2016 national convention in Brooklyn, saying in a formal invitation that the city’s progressive energy would help galvanize the party before the presidential election.

In a letter, made public Friday, to Rep. Debbie Wasserman Schultz (D-Fla.), chairwoman of the Democratic National Committee, de Blasio offered Brooklyn’s Barclays Center arena as the central venue.

With more than two years to go before the November 2016 election, Hillary Rodham Clinton, the former first lady and secretary of state, who was also a U.S. senator from New York, is considered the Democratic front-runner if she decides to enter the race.

But Clinton’s potential candidacy has caused some disgruntlement in the liberal wing of the party, which counts de Blasio as a standard-bearer.

Party conventions are held the summer before the autumn election. In recent decades, New York hosted the 2004 Republican convention that nominated President George W. Bush for a second term and Democratic conventions in 1976, 1980 and 1992. Those events were held at Manhattan’s Madison Square Garden.

The deadline for cities to volunteer to host the 2016 convention is the close of business Friday, said Lily Adams, a spokeswoman for the Democratic National Committee, which organizes the convention.

Adams declined to name the cities that have submitted bids, saying a final decision would be announced by early next year.
