Stephen Harper has hit the ground running after having secured a stronger minority government in Tuesday's federal election.
What's mean on the blue part?
I'm not a teacher.
There is a reasonable interpretation of the expression in question:
hit the ground running = seize an opportunity; begin at full speed, to begin a venture with great energy, involvement, and competence. For example, As soon as the front office gave its approval for the new department, we hit the ground running. The origin of this term is disputed. It may come from troops dropped into a combat zone, from stowaways jumping off a freight train as it nears the station, or from Pony Express riders avoiding delay when they changed mounts.
