City council member: Despite the city's desperate need to exploit any available source of revenue, the mayor has repeatedly blocked council members' attempts to pass legislation imposing real estate development fees.
Conclusion (it is clear that = opinion)
By blocking council's attempts to pass legislation that would impose real estate development fees, the mayor is sacrificing the city's interests to personal interests.
Intermediate Conclusion (thus)
The mayor has a strong financial interest in the matter of real estate development fees.
Evidence
The mayor's family is heavily involved in real estate development.
Evaluate
Since two reasoning moves are made, we can potentially scrutinize each of them.
Given that ... the mayor's family is involved in real estate development,
Should we accept that ... the mayor has a strong financial interest in the matter of real estate development fees?
No, not necessarily. It sounds like members of the mayor's family have a strong financial interest in these fees, but we have no idea whether the mayor benefits from her family members' real estate financials. Do they share money with her? Are they even in touch with her? If she's estranged from the family, the fact that they are involved in real estate doesn't really affect her.
Given that ... the mayor has a strong financial interest in the matter of real estate development fees,
Should we accept that ... by blocking this bill the mayor is sacrificing city interests to financial interests?
No, blocking the bill might still be in the city's financial interests. After all the mayor cites figures that show these fees would cause a net loss of revenue for the city.
So isn't blocking the bill in the city's financial interests?
