I'd like to ask about the meaning of the phrase "by a long measure" in the following passage.
But people absorbed the news with surprise and resignation. Which was a little dissapointing, curiously enough. It would have made Jopale feel more secure about his solution -- more optimistic by a long measure -- if what he was doing caused pointed hatred in the people that he was prepared to leave behind.
Does "more optimistic by a long measure" mean "more optimistic for a long time"?
