> After promising "no new taxes" during his campaign, he later agreed to do the fiscally responsible thing and raise taxes in order to offset spending increases.

That is an extremely charitable parsing of the events. 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".

My take away is to learn not to promise overly optimistic outcomes when your political rivals have a significant stake in seeing you either be a success or a failure.

Edit: Not sure why this was flagged. Did not mean to come off as hostile or aggressive. Anyways, cheers.
