"almost have been ghosted by Jefferson"?

1) Does "almost have been ghosted by Jefferson" mean "almost have been haunted/deeply disturbed by (Thomas) Jefferson"?
2) Does "The deist God is certainly an improvement over the monster of the Bible" mean "The India's deist God is certainly an improvement over/surpass the monster (referring to Jehovah - the God of the Old Testament?) of the Bible"?

Context:

Nehru's definition of the secular India of Gandhi's dream (would
that it had been realized, instead of the partitioning of their country
amid an interfaith bloodbath) might almost have been ghosted by
Jefferson himself:
We talk about a secular India . . . Some people think that
it means something opposed to religion. That obviously is
not correct. What it means is that it is a State which
honours all faiths equally and gives them equal oppor-
tunities; India has a long history of religious tolerance . . .
In a country like India, which has many faiths and religions, no real nationalism can be built up except on the basis of secularity.

The deist God is certainly an improvement over the monster of
the Bible. Unfortunately it is scarcely more likely that he exists, or
ever did. In any of its forms the God Hypothesis is unnecessary.*
The God Hypothesis is also very close to being ruled out by the
laws of probability. I shall come to that in Chapter 4, after dealing
with the alleged proofs of the existence of God in Chapter 3.
