What about Bill Clinton? He “promised” (he specifically used that word) to rebuild “all” of America’s infrastructure. “All” of it.
Imagine this in his voice " I wanted to, really, really wanted to rebuild all of America's infrastructure, but those mean spirited Republicans wouldn't let me spend the money". So you see he didn't break his promise, Republicans did and, hey, just by saying he was going to he did! In demonrat speak anyway.
