I don't think it is, to be honest.

Politics - particularly politics relevant to large democracies - appears to be a function of visible truth, and not truth itself. See all the articles about "X slams Y" or the endless "we're launching an investigation into [thing we cannot prove]".

Anecdotally, from one attempt at chatting with it, Grok is far and away the most obviously dishonest and shifts conversations towards right leaning talking points.

Maximally truth seeking indeed.
