My New Political Map

I devised my own geopolitical map of the united states with borders based on geographic, political, demographic, ethnic and cultural boundaries:

Here are some region names:

• Continental Divide
  
• Tidewater South
• Gulf Coast
• Deep South
• Tornado Ally
• Little Scandinavia
• Piedmont South
• Upland South
• Bluegrass/Bourbon Country + "Middle Tennessee"
  
• Rust Belt
• The Maritime Provinces
  
• Northeast Corridor/Boswash
• Laredo
• LA Metro
  
• Mormonia
• Cascadia
• Silverado
• Greater Bay Area
  
• Phoenix/Las Vegas/San Diego --- name ideas?
• Chicagoland (might be annexed by Rust Belt)
• Upstate
• Northern Uplands
• South Florida
• Interior Plains

Any other name suggestions will be fielded
