Who knows if it even makes it out of the House. They wrote the bill largely in secret again and didn't consult their caucus for the input or opinions on various provisions. R's from states with relatively high property taxes and state income taxes (IL, CA, NJ, NY) have strong reasons to object to this bill since it basically deliberately harms blue states.
They'll get something passed at some point, and it'll largely be bad, but I'd be shocked if it's by Christmas and anything close to what this bill is.
