Democrats are eyeing midwestern cities such as Chicago, Detroit and Cleveland as possible host cities for the 2016 Democratic Convention.

Other cities being considered for the honor are Indianapolis, New York City, Columbus, Atlanta, Pittsburgh, Las Vegas, Miami, Nashville, Philadelphia, Orlando, Phoenix and Salt Lake City.

The Democratic National Committee sent a letter Monday to the mayors of the 15 cities, asking them to submit proposals to host the 2016 Democratic National Convention, according to the Detroit Free Press.

The cities have until June 6 to submit their requests for proposal, and the DNC will make the decision by the end of this year, or by the end of 2015.

"This quadrennial convention is not just the place where we will nominate the leaders of our party and our country, but it is also an opportunity to provide our Host City with a chance to showcase its community on a world stage," DNC Chairwoman Debbie Wasserman Schultz said in her letter to the mayors.

Wasserman Schultz, a Florida congresswoman, said Democrats want a city to host that "shares our values of equality, inclusion, diversity, respect and dignity."

She added that the DNC wants the host city to have "strong relationships with organized labor and those they represent," considering the security and construction that is needed to organize the event.

A political convention brings a great deal of revenue to the host city. The Democratic National Convention in 2012 in Charlotte, N.C. brought an estimated economic boon of $164 million to the region.

Some cities, such as Columbus, Ohio, have made it clear that they want to submit a proposal to welcome the Democrats in 2016.
