Step-by-step explanation:
Caricaturist that draws a politician with an exaggerated mouth is probably suggesting that this politician talks too much. It can be that politicians in question appears often in the media, having opinions about everything even when no one asked him or her. It also might be that the politician is “all work no action”, meaning they give a lot of empty promises without fulfilling anything, always speaking about what they will do, but never actually doing it. The exaggerated mouth will most likely be the critique – the artist probably finds this political figure to be a chatterbox, talking emptily and without the point, just to attract attention, even when they don’t have anything smart to say.
We know this meaning might be true because caricatures in the political context are usually satirical, trying to convey critique of a certain person or event in a humorous tone and in a symbolic way.
