“Leaning forward” as in “leaning forward in the saddle” means to think and look ahead and take some preemptive measures to counter a potentially serious situation rather than just reacting as the situation unfolds.
A rider leans forward so as to not fall off the horse when it has to jump over an unforeseen obstacle or dangerous thing along the trail.
Also the MSNBC liberal motto which I think was the intent of usage.
Ha...it’s like “leading from behind” in reverse....
