Grit: not just a measure of athletic prowess anymore

I was reading The Boston Globe's endorsements (today is the Boston mayoral election in which Tom Menino, the 16-year incumbent, will stand for an unprecedented fifth* term; there are also several city council and local races) and came across this tidbit I could not resist sharing. With a nostalgic nod to the glory days of FJM:

[The Globe urges] readers in Newton to support Ruth Balser for mayor. Currently a state representative, Balser has shown a commitment to her community and much-needed grit.

Emphasis on grit added.

*I like Menino well enough. Having recently moved out of the Hub I no longer have a horse in this race but the very idea of five terms in office is an insult to the ideals of good government.

I mean it's not like the most powerful federal legislative body can stay in office for life, right? That would be absurd.
