This is my proposal to split it:
Blue: leftist west-coast nation (I had to use Arizona as a connecting point with New Mexico and Colorado, sorry) [oh and add Hawaii]
Name: The United West Coast States
Red: right-wing middle nation
Name: The United States of America (the others would be splitting FROM them)
Rusty: centrist working-class flip-flop nation
Name: The United Mid-North States
Green: leftist east-coast states (imagine a general election with Elizabeth Warren, Bernie Sanders, Michelle Obama, Hillary Clinton, etc.

)
Name: The United East-Coast States
Pink: The Republic of Florida
get rid of alaska, give it back to russia or something
