When Thomas hits he's on-point, and his style of writing is the most approachable to a non-jurist like myself (Thomas himself was only a judge for 18 months before being appointed to SCOTUS). Breyer's legal approach primarily revolves around more functional or practical concerns, which is a nice reprieve given how much more ideologically-animated the Court has recently become.
I'm not so much of a partisan hack. I can admire qualities of both liberal and conservative jurisprudence.
Oh it's not that. They just seem like weird choices from either end of the spectrum. I think the best thinkers on the right are clearly Gorsuch and Roberts (not even because they're more likely to swing, but because they have a more coherent and smart philosophy than Alito/Thomas/Kavanaugh. Scalia would have belonged in this group as well.) Breyer I get, but him+Thomas just seems like a weird pairing. Frankly, I'd have thought you'd prefer Kagan.
