Probably true. VP's are often chosen pragmatically, and don't reflect ideals.
I haven't seen enough about Buttigieg's politics to know much about him. I'm sure he has a decent character, but I'm unconvinced he's prepared to be president in such a troubled nation. He reminds me of Obama, and not in a good way. Obama was a flawed figure that trusted too much in the neoliberal myth and not enough in making tough decisions with moral clarity that wouldn't win him any friends among his peers. After the 2008 financial crash, our country needed a liturgy of public repudiation of private greed, instead we got Obama's promise that nothing would fundamentally change for Wall Street, and he had their backs. Instead of systemic critique, we got years of posturing identity politics and techno-utopian fantasies while the average Americans standard of living declined, all accompanied by zero empathy from Obama in the process (other than making cold remarks about people clinging to their "guns and religion" in rural America)
So, I'm sure Buttigieg is a decent Christian man and would make a good cabinet appointee, but I wouldn't count on him to make hard decisions that will be contrary his instincts to build a soft consensus. Buttigieg comes across as somebody that wants to be likeable, in an almost desperate way, his whole life has been marred by a self-creation project of acceptability politics. And that's not exactly a good thing right now in this cultural moment.
