In response, I would just say that, yes, I do understand the recent tax bill. At it's core, it's part of a long term plan to reduce government by starving it for money, at the same time it is a giveaway to large campaign donors. These are not speculation, but directly acknowledged by the spineless and craven Speaker of the House Rep. Paul Ryan.
Blue states tend to spend a lot more money on government services, especially education. This makes the taxes higher, but it was evened out somewhat by a reduction in federal tax burden. With that gone, it adds a lot more pressure to tax payers in states with higher property taxes. Those states tend to be blue. When evaluating the wisdom of this change, keep in mind that those states also tend to be net payers into the federal system, while red states tend to be net takers from the federal system. There are exceptions but the trend is clear.
