Most people do stuff because they mean it.

Politicians and some others do stuff because they think it will get them power/votes/money/influence etc.

Their behavior is completely inconsistent with respect to having a stance or opinion. Their behavior is completely consistent with respect to trying to be in a favorable position. Once Trump’s out, they will turn right around and do or say whatever they think puts them on the winning team, even if it’s the complete opposite of what they’re doing now.

It’s plain as day, yet hard to see because it’s so bafflingly spineless.
