Eh, I agree the GOP is reactionary rather than conservative, but I think this is an equal charitable take, especially this statement -

> It's the checks and balances that keep our (ostensible) democracy functioning.

I'm a fan of TR and Eisenhower to a lesser extent, so this isn't exactly a criticism. The US Constitution was definitely founded under the model you describe, but those things aren't necessarily indivisible from each other. The progressive conservatism you defined is a commitment to a hierarchical model of liberalism. Many of the achievements of both Roosevelts and Eisenhower were in the name of warding off Socialist and Communist movements in the early and mid 20th century. They were progressive in giving more rights and services to the common person (well, some of them, some of the time) and conservative in maintaining the ability of the wealthy to continue on with their necks and bank balances intact.

Although some of the critiques of conservative liberalism (as opposed to the historical, royalist conservatism) can be waved off as "the Republicans aren't actually conservative any more", there is a still a valid critique to be made if you believe that 250 years is more than enough time to embrace a more egalitarian model.
