I think this is what happens when court sketch artists go home and blow off steam in MS Paint.

It's a satirical cartoon, which is an art style by itself.

Recognizable facial features are exaggerated for comedy and to highlight the uglyness, yet realistic enough to recognize.

You can tell it's comedy, because the persons don't actuallly look like the hyperbolic cartoon character, but it's still a very personal criticism, because they do have those features, unlike any other person. The name tags in the image are redundant.

It must be getting more difficult to make with modern celebrities, who already look like satirical figures in real life due to botox, spray tan and fake hair etc.

Satirical cartoons are important. Even if the political point is blown out of proportion like the drawing itself, it usually shows some truth or at least something that could be true, and thus basically states the lowest common denominator for understanding the actual politics for the reader to relate to and form their own opinion.

It's sort of "let's play with the worst possible interpretation of actual events".

Regardless of the person actually being a good or bad politician , there will be satirical cartoons made to critizize them from this "low brow* point of view, that they ought to be able to handle or even admit to and laugh along with. So, it gets even more funny if the targeted person reacts negatively towards it.

I heard the young 'uns call it "boomer comic".
