The Democratic National Committee has asked Philadelphia, Pittsburgh and 13 other cities to make a pitch to host the presidential nominating convention in 2016.

The DNC on Tuesday said the party will accept proposals through June 6 and will pick a host city either late this year or early in 2015.

IIn addition to Philadelphia and Pittsburgh, the cities under consideration include: Atlanta; Chicago, Cleveland; Columbus, Ohio; Detroit; Indianapolis; Las Vegas; Miami; Nashville; New York; Orlando; Phoenix; and Salt Lake City.

Some cities seem more likely than others. For instance, President Barack Obama, who will be leaving the White House in 2017, calls Chicago home, and his potential successor, Hillary Rodham Clinton, is from Illinois. Clinton also represented New York in the Senate.

A nonprofit group of political, labor, business and community leaders, chaired by former Pennsylvania Gov. Ed Rendell, began last month putting together their pitch for Philadelphia to host the convention at the Wells Fargo Center.

Supporters said the convention could pump $300 million into the region's economy.

The city last hosted a political convention when the Republicans first nominated George W. Bush in 2000.
