If there were somehow a vote to split the US along political lines, which states would vote for it?

If the vote were just held without an outpouring of support for it, it would fail in every state. I've often wondered what would happen if there were independence movements in the U.S. as strong as those in other countries like the U.K.

Like if instead of the Scottish National Party (SNP), we had a California National Party that took California and its votes from the Democrats permanently ensuring that Democrats could not win a majority and hurting Democrats in unionist battleground seats in other seats. Republicans would be in charge even more and the Californian Independence Movement would become even more popular and it would escalate until there was a referendum of some sort.

But hey, just speculation.
