I think in the context of the current presidential race, Amy Klobuchar could be closest to described as an intentional moderate. Namely someone who focuses on simply just changing laws at the cost of any sort of deeper ideological belief, at least with regards to how she frames her view point rather than by defending her proposals within their own merit she focuses on the compromise aspect. Biden on the other hand is clearly a traditional liberal, not a social democrat, socialist, or progressive. At the same time, George H.W. Bush, or even Mitt Romney, are also a liberals in the same sense, with both politicians being pulled in different directions because of where their party currently stands. This sort of view point isn't moderate in any sense of the word, a liberal, who believes in free markets and has a globalist world view is a unified political theory for how things should be done. However, a person who is an accidental moderate themselves, who never developed their own or latched onto any unified broad political theory, would tend to support candidates like the above because the American political system tends towards liberal capitalism as being the political center.
