That's a Great Question

 I detest hearing any politician reply to a citizen, "That's a great question."

Translated, that means the citizen caught the politician in a lie or the politician got caught feeding the populace bull s+*t and the politician does not have a clue, either. 

There is something very condescending and patronizing about hearing, "That's a great question."

Below is a pathetic example, but you will get my vibe.

Citizen:  You want to promote density housing with no parking as the government is pushing public transportation and electric vehicles.  Yet there is no plan for parking nor where people would charge their electric vehicles.  Public transportation is inadequate to get people and families to their jobs, schools, doctors appointments, etc.  Exactly how will people get around, where will they park and charge their electric vehicles with all this new density building with no parking and no real public transportation system, and how do we meet our carbon emission reduction goals simultaneously?

Politician:  That is a great question!

Bottom line:  Hearing "that is a great question" is the equivalent of hearing "I have no effing idea myself and I am full of bull-oney."  Any political campaign manager who encourages his client to use "that's a great question" when caught in a lie or flat-out does not know the answer should be fired immediately.
