As mentioned, the convention center needs to have a minimum of 600,000 contiguous square feet. Unrelated to venue availability, scheduling, costs, fees, hotels, etc,... I might be missing one or two, but these are pretty much the only convention centers that they will consider:

McCormick Place
Las Vegas Convention Center
Orange County Convention Center
Georgia World Congress Center
New Orleans Convention Center
World Equestrian Center
International Exposition Center (I-X Center)
Kay Bailey Hutchison Convention Center
Pennsylvania Convention Center
Sands Expo and Convention Center
Mandalay Bay Convention Center
George R. Brown Convention Center
Jacob K. Javits Convention Center
Donald E. Stephens Convention Center
Huntington Place
Moscone Convention Center
San Diego Convention Center

And of these with the space requirements need to be available on the date windows the National is shooting for.
