Ok from what I get they are conservatives which support a welfare state? Since People Like teddy and Bismarck were still reactionary social conservatives. We had something like this in britain under the tory party in the 1920/1930s. Might as well drop the 'progressive' label since they're still staunchly racists.
It's an interesting symptom actually, those people like Bismarck originally adopted the "progressive" label because they wanted to have some social safety nets (with obligatory remember that such nets were understood by them as the safety for the ruling class from revolution first and foremost), and now, after neoliberalism dismantled so much of the working class achievements, this label is back because the need for such safeties is indeed seen among some conservatives again.
In Canada, our conservative party calls themselves the Progressive Conservatives (PC). They're both racist and constantly working to dismantle what little social safety nets we have left. I have no idea what's so progressive about them.
