Can we draw the following hypothesis from the context?

Context:

Nicholas Sposato serves on Chicago City Council as alderman of the 38th Ward of the City of Chicago on the city's Northwest Side. Sposato was elected in 2011 in an election against incumbent alderman John Rice, who was endorsed by then Mayor-elect Rahm Emanuel.

Hypothesis: Rahm Emanuel did not want Nicholas Sposato to win the election to serve as Alderman in 2011.
Yes
