more motivated by our dislike for the GOP than our affection for our policies, we would transform from being a political party to an identitarian party (like the Republicans are), meaning we would vote like hell in bigger numbers, we would vote in every election like our lives depend on it, because "winning" would be more important to us, almost like fans of a football team need compulsively to win every week. He's talking about our primitive wiring here, and what decades of studies and also Game Theory can teach us about adjusting our party a little bit to be more effective.

Democrats (on-the-street, average Dems) would be as obsessed with politics as even average Republicans are.

The dark side of this is, obviously, that we become a party whose energy is derived from opposing something, instead of our trademark reputation for being the party of hope and regeneration. But I don't think it's wise to dismiss this theory out of hand, because we only need to look at the Republican party to see how well it can work. We would play the long game better.

The Republicans are sure making it easy for us to coalesce around the idea that the GOP is the anti-Democracy party, which makes our job so much easier in terms of deciding what we are for and what we are against.

One of the panelists on MSNBC just literally said what you wrote: Marjorie Taylor Greene is the face of the new Republican Party.

Even if she's gone, we can probably still make this stick with people like Gatez, Jordan, Cruz, Hawley.

But Taylor-Greene is most certainly a lightning rod, almost a caricature of what we have noticed all along about the GOP under Trump.

So I wouldn't dismiss your point at all. Even if she goes, your essential point is important IMO.
