Combining the two: centrists have bad vibes because they always have an authenticity problem. They position themselves against change, but then happily go where the Overton window takes them (see Biden’s outgoing border bill). They are for nothing except what they think is popular at the moment, which is usually out of date information, and that comes across as fake and focused on accumulating power rather than solving problems. You don’t need to be a policy wonk to see that centrists will say anything to get your vote and do nothing to solve your problems
