Read Genesis chapter 18, God’s conversation with Abraham. Abraham brought the number down to ten individuals. Surely there are more than ten in “blue” states.
I've heard ministers say if Abraham had been persistent he could have gotten it down to one. Possible, but unknowable.

The city of Nineveh, because of the obedience of Jonah - reluctant as it was - was brought to repentance and had its life extended significantly.
I'd love to see America repent and have our Republic renewed and extended.
