To demonstrate something about capitalism, one should use an example from capitalism, not try to contort something from government into capitalism.
Capitalism tends towards winner-take-all systems, but not all winner-take-all systems are capitalistic. I find the example fitting.
Use an example of capitalism to justify an example of capitalism. If capitalism is a winner-take-all system, there should be endless examples.

Also see the pharma industry, right? The US government isn't all governments either, in some countries parties actually rule together, compromise and whatnot. And considering getting money out of elections isn't even attempted in earnest, the question really is what is the tail and what is the dog here.
It just means things are a lot more "costly" for Blue and/or Blue things (like climate change policies).
But of course in the primary layer a lot of things become infinitely costly for Blue things. (Because they fall under executive rights.) But there are a lot of other layers. (State legislatures/governors, city level issues, and so on.) And though a higher layer can force things on a lower layer, but it's not zero-cost, so usually things settle into an ugly compromise.
