I often wonder who these are for. It makes no attempt to engage in an honest way with criticisms and hesitations that non-Democrat voters have so it doesn't have any ability to persuade them. It also infantalizes the view points of both the republican opposition and anyone outside the two party system so it's not helpful for self-critique for "centrists". So as far as I can tell it's just red meat aimed at Democrat supports to keep them all hopped up and believing that they are "the party of responsible governance" (in comparison to the Republicans) and therefore all criticism is invalid and everyone else is childish. Like, if this is supposed to be something else you really need a new way of engaging, because this "there is no alternative" shit is what turned me away from Democrats back in the Obama years.
