Whether he promises it or not, the president cannot just simply say "free cookies for everyone" and poof, its done....keep in mind that there are 538 congressmen that would have to agree with the president by at least a 2/3 vote. It is already difficult enough for relatively legit bills to be passed, so something that would clearly hurt the country wouldn't have a chance of passing at all. And if someone were to run for congress or president and promise "free cookies", then if their opponent wasn't an idiot he would ask them where those free cookies would come from and how are they not going to hurt the economy, and he better have a good response to that or people aren't going to go for it.
