The headline on CNN late last night apparently described Scott Walker as “narrowly defeating” Barrett. Ultimately he beat him by 7% of the vote.
Now, some may call that narrow, but most would not. Words like that are dangerous because they can obscure your view of the real numbers. Other words that can skew your view are “spike” “surge” “plummeted” etc.
While all probably at least indicate the direction of the change, there is no standard for how big the change must be to use one of these words. If possible, check the numbers first, then the headlines.
It’s better than trusting journalists.
