It's been pointed out by many others, but the real deception in this bill is that the middle-class cuts expire after only 2-4 years, and after that many people will actually see their taxes increase, at least slightly. The wealthy and corporations, however, will continue to benefit. Furthermore, many of the costs of the bill are also pushed down the road. It is certainly a clever piece of legislation, in that voters in 2018 will probably see at least some minimal tax cuts, which the GOP clearly hopes will help them in next year's elections. I've read that the Koch Brothers are already planning to spend big bucks soon on a propaganda/commercial blitz to win support for the cuts. What Republicans are clearly hoping (banking on, really) is that the short-term cuts will win over voters in next year's elections, allowing them to stay in the majority until 2020, and by the time the real costs of the bill set in (steadily increasing deficit, leading to significant cuts in Medicare, Social Security, and other welfare programs, tax increases for the middle class) it will be too late to alter them.
