Getting elected involves compromising your values.
Usually, when people say "compromising values", it carries a connotation of low integrity. That's not really my intention here. Instead, I mean it in a more neutral way: if you're running for office, it's pretty likely that your values will be out of step with your constituents' values in one way or another. Maybe you have a wider moral circle of concern, or have a stronger sense of justice, or whatever, leading to you holding views that are unpopular among your constituents.
This makes you less likely to win. And so, you have three choices:
1. Stick to your values, tanking the decreased likelihood of winning
2. Change your values, or at least commit to acting on your constituents' values rather than your own
3. Deceptive alignment: Run on your constituents' values, but once you're in power, act on your own values
Options 1 and 2 trade off against each other, and different politicians have reputations for being at different points on the spectrum. For example, Bernie Sanders is thought of as pretty close to 1, while Gavin Newsom is thought of as pretty close to 2.
The most clean-cut example of #3 that I know of is Jimmy Carter, who deliberately tried to appeal to segregationists in his campaign for governor, but then famously declared that "the time for racial discrimination is over" in his inaugural address. I find this interesting to think about, because I think that racial discrimination is bad, but at the same time I think it's a bad policy to be deceptively aligned to your constituents.
Anyway, I sometimes think about this in the context of electing AI safety champions to Congress. I think the value proposition is great, but the more they take route 2 over route 1, the lower the value of electing them. (Meanwhile, I think that AI safety champions should steer away from route 3, though in my opinion it's fine to place a different emphasis when campaigning than when policymaking.)
