I don't believe so, but they are a very vocal demographic and in many respects have superior communication skills. Right leaning ideologues in recent years often come at discourse as a competitive sport or a kind of cognitive warfare, whereas liberals and leftists are more concerned with gaining external approval (of an audience or some third part) and pursue some sort of objective correctness or consistency, often tot he detriment of the argument they're making.
So while there are not that many MAGA types, they tend to punch above their weight in terms of what passes for debate on social media. Conversely, I'm nots ure as many liberals would leave as threaten to, because where would they go - Mastodon? Discord? People use twitter because it's a large flat platform rather than one with a lot of silos. That's why things can go so viral so quickly, but also why there are so many dumpster fires; anyone can find and address/respond to/ be seen by anyone else, with no need to know the address of the super sekrit server where the cool kids hang out.
I do think the likely outcome of all this is best visualized as a smoking crater surrounded by poop emojis, and have my doubts that large advertisers will want to associate their brands with it. On the other hand all sorts of other trash is commercially successful for reasons that completely elude me.
