> The more accurate (realpolitik) version is Bush said the no new taxes quip, and Democrats subsequently laser-focused on making him (slightly) raise taxes, showing he is a "liar".
These days I think a Republican president in the same position would be a lot more likely to refuse to sign it, even it if meant shutting down the government. But politicians (and voters) really were much less divided back then compared to today.

Over-promising is the bread and butter of campaign rhetoric; candidates do it all the time (certainly in US presidential elections at least). If it was really that much of a problem in practice, you'd see more election winners who hadn't previously promised all kinds of things they have no chance of delivering.
