General Discussion

there is really no such thing as Red States and Blue states. That was a term invented by USA Today during the 2000 Presidential election.

There are states where the majority of the voters vote one way or another but it is not necessarily state wide.

The division is mostly along the lines of rural v urban areas. For instance, Tennessee is Red but Memphis is Blue. Illinois would be Red except for the large population of Blue Chicago.

There are some exceptions, like the "Black Belt" that votes Democrat in Red Alabama or the Democrat area along the river in the state of Mississippi. Some of the NE Blue states are very Blue statewide, like Mass.

You see this very clearly with a map of the R v B counties in the US.

Secession would not be as clear as it was in 1860.
